10 Shop Safety C. General Shop Guidelines The hazards associated with shop work require special safety considerations. Whether you work in a metal, wood, glass, or electrical shop, the potential hazards for personal injury are numerous. This section highlights essential safety information for working in a shop. Shop Access Only authorized users (as defined by the department and its representatives) should have access to shop spaces. Training may be required before shop access is granted. Disposal of Oily Towels/Rags Oil or solvent soaked rags are a fire hazard and should be disposed of in an approved metal container. General Shop Safety The following general safety practices apply to all shops at Iowa State University (ISU). Shop supervisors may apply rules and enforce requirements that are more restrictive than the minimums listed below: • Always wear appropriate personal protective equipment (closed toe/heel shoes and safety glasses). • Avoid practical jokes or other disruptive behavior. • Tie back long hair, restrict loose clothing and jewelry. • Food, drink, tobacco products, gum, medications, and cosmetics are not allowed in work areas. • Avoid distractions (ear buds, cell phone, etc.). • Avoid working alone in the shop, but when unavoidable, make arrangements with the shop supervisor, or a colleague to check on your status periodically. • Obtain approval from the shop supervisor before using any machines or tools. • Know the hazards associated with the work. • Ensure you are fully educated on the proper use and operation of any tool before beginning work. • Ensure adequate ventilation to prevent exposure when working with glues, lacquers, paints, dust, and fumes (welding.) • Ensure equipment guards and shields are in place. • Return tools to their proper locations. • Report damaged equipment to the monitor or supervisor. • Keep all work areas and aisles clean and unobstructed. • Know emergency procedures. Hair tied back Flammable safety can

11 Shop Safety • Report injuries to the monitor or supervisor. The elements above should be posted using the Safety Rules Poster. Hazardous Chemicals or Waste Ashop using hazardous chemicals (solvents, paints, etc.) must comply with the OSHA Right-to-Know standard. Safety data sheets (SDS) for all of the chemicals or product in the shop must be available to all users, and an annual chemical inventory must be submitted to EH&S. Waste must be handled in accordance with Waste and Recycling Guidelines. Waste or unwanted chemicals must be accumulated in designated Satellite Accumulation Areas in the same room or suite of rooms where they are generated. The accumulation area must be marked by an orange sign (see Postings and Signage). Chemicals cannot be moved across hallways or between Satellite Accumulation Areas. Request collection by submitting an online request. Housekeeping The shop supervisor will ensure the shop is properly cleaned at the end of each work period, and that all waste is disposed of in accordance with ISU policies. Tools, materials, and equipment should be returned to their proper storage locations at the end of work period. Maintenance and Inspection Shop equipment must be maintained according to manufacturer’s specifications or established guidelines. Inspections of equipment for damage, corrosion, wear, contamination, must be performed and documented on a routine basis. Damaged or defective equipment must be tagged or removed from service. Unsafe equipment tags are available from EH&S. Postings and Signage Postings and signage are used to identify hazards, communicate procedures to follow, and provide guidance during emergencies. The Safety Rules Poster containing the minimum requirements for working in each space, shall be displayed at the shop entrance. The poster must be tailored to the specific hazards in the shop environment. The interior of the shop must be posted with the following: • The Hazardous Waste Satellite Accumulation Area sign contains emergency contact information, container type, labeling requirements, and EH&S contact information. Place the orange sign where you intend to accumulate waste or unwanted chemicals for collection. Consult the Waste and Recycling Unsafe Equipment Tag Label • Label the container “Hazardous Waste” • Identify the hazards, such as flammable, corrosive, toxic, etc. • Describe the contents • Spell out abbreviations • Close the container so it won’t spill if tipped over (no foil, parafilm, etc.) • Vent as necessary to prevent overpressure • Remove funnel after use Lid • Use waste containers that are compatible with the contents • Segregate incompatible materials • Use secondary containment to capture leaks • Maintain your spill kit with appropriate materials; restock after each use Leaks • Keep waste in the room where it was created • Dispose of waste containers at least every 90 days • Contact EH&S immediately if you have 55 gallons of hazardous waste or 1L of acutely toxic waste Location For emergencies, dial 911. Clean up small spills immediately.

12 Shop Safety Guidelines for details. • Signs identifying the locations of safety equipment (fire extinguisher, safety shower, eyewash fountain, etc.) are required. Refer to specific information on signage requirements and posting locations as discussed in the Safety Equipment section. • Signs, labels and/or warning/caution tape should be used to identify designated use and storage areas for materials or equipment requiring special procedures (welding). • Post hazard communication signage at the main entrance to the shop. The door signage program requires a current chemical inventory. If you have questions about required signage please contact EH&S at (515) 294-5359 or EH&S. Shop Safety Survey EH&S has a formal Shop Safety Survey program. Routine shop safety surveys are completed to identify unsafe conditions and identify areas of improvement. Shop supervisors are required to perform annual self-inspections using the Shop Safety Survey. Documentation of completed inspections must be maintained by each shop or department for a minimum of three years. Surveys are performed by EH&S periodically and assistance is provided to help protect workers from accidents, illnesses, and the environment from harm. Site Specific Safety Site specific safety measures, in addition to general shop safety guidelines, will be developed based on specific hazard analysis of the shop space and equipment. Site specific safety measures can include, but are not limited to additional or specific PPE, training, rules, competency validation, or environmental controls. Standard Operating Procedures Written standard operating procedures (SOPs) are recommended for all operations involving hazardous chemicals, machinery, or processes. An SOP provides a standardized reference during instruction, training, and competence verification on individual machines or processes. For assistance, see the SOP Development page. Tool Inventory Shop equipment should be inventoried using an equipment inventory form that includes the equipment type size, manufacturer, model number, serial number, and university id number.

13 Shop Safety D. Safety Practices for Specific Hazards The following safety practices apply to Iowa State University (ISU) shops where specific hazardous materials or processes are encountered. Compressed Gases Compressed and liquefied gases pose significant chemical and physical hazards to shop users. The ISU Gas Cylinder Safety Guidelines provides additional information, including leak procedures. • Ensure gas cylinders are secured, stored away from heat sources and capped when not in use. • Ensure hazardous gas (corrosive, flammable, and toxic) quantities are below maximum allowed volumes and are stored in a ventilated cabinet when required. • Transport cylinders on freight-only elevators where possible to avoid potential exposure to passengers. • Do not ride with gas cylinders in elevators. • Use an appropriate hand truck or cart to transport gas cylinders (do not drag or roll), ensure the valve protection caps are in place, and handle only one container at a time. • Ensure proper maintenance and use of regulators, manifolds, and safety valves. • Always wear safety goggles when performing any operation with compressed or liquefied gases. Additional protection may be required based on the gases used (face shield, insulated gloves, chemical resistant gloves, and/or an apron). • After assembly of a gas supply system, test all connections using a soapy water solution or a gas detection device. Retest the system periodically and when leaks are suspected. Refer to the Compressed Gas Leak Procedure if a leak is detected. Electrical Safety Electrical voltages as low as 12-volts, can be dangerous and cause injury. When working with or around electrically powered equipment follow these general precautions: • Shop equipment must be powered by an appropriate electrical source matched to the power requirements recommended by the manufacturer. • All electrical equipment must be UL listed and have either a grounded plug (three prong) or be double insulated. • Protect electrical power cords from damage. Immediately replace cords that are worn, frayed, or otherwise damaged.

14 Shop Safety • Extension cords are to be used only for temporary use (less than 72 hours). • Electrical equipment used within six feet of water or in wet/ damp environments must be plugged into a Ground Fault Circuit Interrupter (GFCI). • Do not connect multiple pieces of equipment to the same power source. Shop equipment should be plugged directly into a wall outlet and not a multi-plug power strip. • Grasp the plug to remove it from the socket – never pull the cord. • Always unplug electrical equipment before attempting any repair or maintenance. Hand, Portable, and Stationary Power Tools Hand tools are non-powered tools such as saws, screw drivers, hammers, chisels and wrenches. Hand tools should be properly maintained after each use. Portable power tools are powered by an electrical power source (cord or battery) or gasoline. Examples include: drill, circular saw, grinder, router, jigsaw, and sander. Pneumatic tools are powered by compressed air. These include: drill, impact wrench, grinder, ratchet, sander, and a cut-off tool. Stationary power tools are large, non-portable and powered by sources such as electricity, gravity, pneumatic, or hydraulics. Maintain an inventory of power tools and equipment using the Equipment Inventory Form. Follow these guidelines for general tool safety: • Use a tool for its intended purpose and only if you have been trained on the tool. • Inspect all toolsbeforeuse. Repair or replace themwhendamaged or defective and report problems to the shop supervisor. • Keep tools sharp. • Direct sharp cutting tools away from yourself and others • Keep all guards in place. • Avoid distractions and pay attention when operating power tools. • Do not rely on strength to perform an operation. The correct tool, blade, and method should not require excessive force. • Never reach into the point of operation while equipment is running. • Disconnectorunplugthepowersourcebeforeclearingjamsorblockages. • Never disable or tamper with safety releases or switches. • Whenever possible use a push stick or pad to move material through a machine. Note: Use the right tool for the job.

15 Shop Safety • Keep a firm grip on portable power tools. • When possible, secure work pieces with a clamp or vise. • Keep bystanders away from moving machinery. • Store tools in a manner that prevents them from being damaged. Laser Safety Class 3B and 4 lasers emit amplified visible and non-visible light radiation and may cause immediate harm to eyes and skin. All users of Class 3B and 4 lasers must be pre-approved by the Laser Safety Officer and must adhere to the safety requirements outlined in the Laser Safety Manual. Refer to Laser Safety web page for more information. Lockout/Tagout (LOTO) Lockout/tagout (LOTO) procedures are required when unexpected energization of equipment duringmaintenance or service could cause injury. LOTO procedures are described in the ISU Lockout/Tagout Manual and must be performed by trained personnel authorized to perform maintenance or service on powered equipment. LOTO procedures are not required for work on equipment that can be unplugged and controlled from the power source. Machine Guarding Moving machine parts must be safeguarded to protect operators from injury. Belts, gears, shafts, fly wheels, chains, and other moving parts must be guarded to prevent contact with the operator. Guards must prevent individuals from coming into contact with the hazard, without creating additional hazards, or preventing the individual from performing routine tasks. If at any point a guard needs be removed, LOTO procedures must be followed and the guard replaced after performing the required task/maintenance. Noise As many pieces of shop equipment produce sound levels that can be damaging to hearing, hearing protection may be required during use. The shop supervisor must ensure that noise hazard areas or equipment requiring hearing protection have signs or are labeled. Refer to the ISU Hearing Conservation Manual for more information. Respiratory Hazards Fabrication, finishing, or painting operations may produce hazardous levels of airborne dust, particulates, or vapors. Engineering controls such as ventilation hoods or snorkels may be in place to mitigate these hazards. However, if these controls are not feasible, respirator If you notice that a guard is missing or damaged, contact the shop supervisor.

16 Shop Safety use may be an appropriate means of protection. The issuance of respirators to employees must be completed as specified in the ISU Respiratory Protection Program to ensure proper respirator selection, fit-testing, medical surveillance, and to meet regulatory requirements. In some cases shop users may choose to voluntarily use a respirator even if it is not required. Voluntary respirator use is also subject to certain requirements as outlined in the ISU Respiratory Protection Program. Welding and Cutting Welding and cutting are two forms of hot work that require special safety considerations. These operations must be performed in a designated area by trained individuals, with appropriate SOP’s including PPE requirements and ventilation instructions. Hot work operations that cannot be performed in designated areas must be conducted according to the ISU Hot Work Permit Program. When welding; ensure that the welding helmet visor is dark enough to provide adequate protection. See the OSHA guidance 1910.252(b) (2)(ii)(H) to select the correct shade numbers. Wear fireproof apron and gloves. If necessary, use a welding curtain to protect bystanders from UV radiation. In addition to the general guidelines for welding and cutting, follow these specific guidelines for safe welding operations: • Ensure theweldingareahasanon-reflective, noncombustiblesurface. • Ensure that adequate ventilation is installed and is functional. • Ensure that electrical cords are properly grounded. • Keep cylinder fittings and hoses free from oil and grease. • Ensure acetylene/oxygen systems are equipped with flame or flashback arrestors. • Replace defective or damaged hoses. • Carefully purge hoses and torches before connecting to a cylinder. • Always use the minimum acceptable flow rate. • Never use amatch to light a torch. Use an approved lighter or striker. • Do not tamper with or attempt to repair cylinders, valves, or regulators. • Ensure flammable and combustible materials are not in the vicinity during hot work operations. • Close cylinder valves after each use. Half-face respirator Common hazards associated with welding include: • electrocution • burns • uv radiation exposure • oxygen depletion • sparking

17 Shop Safety E. Emergency Planning Planning for emergencies allows for communication of hazards through signage / postings and enables shop personnel to respond appropriately in emergency situations. Emergency Action Plan Each shop shall develop an Emergency Action Plan (EAP) that provides contact information and procedures to be followed in the event of an emergency such as: • fire • intruder • medical • severe weather • spill or release • utility outage • vandalism Post a shop specific Emergency Action Plan near the shop exit for easy access during an incident. The plan should be reviewed and updated annually. All shop users must be trained on the emergency action plan as part of the site specific training. Evacuation Procedures Aisles, exits, and clear access to emergency equipment must be maintained, to ensure the ability to respond in emergency situations. Post evacuation routes and meeting locations for emergencies such as fire, severe weather, and chemical spills. Building Evacuation Maps are available on the EH&S website. Identify building alarm pull station locations (fire alarm, chemical spill, severe weather). Shop employees must know how and when to activate alarms. Fire Emergencies Fire and evacuation alarms alert building occupants to life-threatening situations. LEAVE THE BUILDING IMMEDIATELY IF THERE IS A FIRE OR CHEMICAL ALARM! In the event of a fire Activate the alarm – If a fire has started, no matter how small, activate the alarm system with a fire alarm pull station to alert building occupants. Call 911 – Notify responders. The building alarm should initiate a

18 Shop Safety response, but calling 911 will inform responders there is an actual emergency. You will also be able to provide critical information. Rapid response minimizes loss of life and property. Respond – ONLY IF IT IS SAFE TO DO SO! • Extinguish a fire if you have been trained, the fire is small, and you have a safe exit route. However, you are not required to do this – it is always OK to get out. • Shut down hazardous operations. Exit the building – Leave immediately by the shortest and safest exit route. DO NOT TAKE THE ELEVATOR! • Assist injured or impaired persons if you are able. • Close doors behind you. • Stay low if you encounter smoke. • Refer to your Emergency Map for the nearest exit. • Respond to your Meeting Place. • Do not re-enter the building until the fire department has cleared the building for re-entry, even if the alarms have been silenced. Designated Meeting Place – Gather and stay at your designated safe location. Notify supervisors and responders of: • Injured or disabled persons. • Missing or unaccounted personnel. Provide their last known location or places they might be working. • Hazardous operations or areas in the building. Additional information on how to respond, prevent, and prepare for a fire is available in the Fire Safety Guidelines. Emergency Map

19 Shop Safety F. Training Training plays a role in preventing injuries and promoting safe work practices. Training should be undertaken by new shop users and be refreshed at regular intervals. Satisfactory completion of training must be documented and retained for at least one year after termination or graduation. Documentation should include an agenda describing the training and a dated sign-in sheet for all attendees. The Iowa State University (ISU) Shop/Tool Use Safety Agreement includes a listing of general shop rules and sign-offs as well as spaces for specific equipment authorizations. EH&S Training Safety training is accessible to all faculty, staff, and students through Learn@ISU. Required training for shop users shall include: • Shop Safety Fundamentals • Fire Safety and Fire Extinguisher Training • Emergency Response Guide Video • HazardCommunicationTraining Safety training resources are available on the shop safety web page. • Equipment safety procedures covering operational information on specific pieces of equipment • Tool Box Talks covering shop safety topics • Emergency planning Site Specific Training Training beyond the minimum, site-specific training will be determined by the shop supervisor based on the hazards present and activities performed in each shop space. Shop users must receive site-specific training on the following topics: • Procedures for responding to emergencies as outlined in the Emergency Action Plan. • Procedures and proper use of all tools in the shop area. • Location of references describing hazards and safe practices associated with materials, procedures, or tools (safety data sheets (SDS), standard operating procedures (SOPs), equipment safety procedure). • Physical, and/or chemical hazards in the work area, including signs and symptoms of exposure, allowable chemical exposure limits and protective measures users should take to avoid exposure or injury. • Proper waste management and disposal procedures Document any additional training using the Site Specific Training form.

20 Shop Safety G. Safety Equipment Eyewash An eyewash fountain must be readily accessible in all areas where corrosives, hot liquids, or other eye-irritating materials (formaldehyde) are used or stored. During development of an Emergency Action Plan, personnel must identify eyewash fountain locations, verify proper function, and determine if additional eyewash fountains are required in the shop. Ensure that eyewash fountain locations are marked with a sign, typically green/white, available from Environmental Health and Safety (EH&S) and posted at eye level above the fountain. Eyewash fountains should be flushed monthly by shop personnel. Record these tests on the “Safety Equipment Test Record” tag attached to the eyewash. Fire Extinguishers Each shop must have unobstructed access to at least one fire extinguisher located at or near an exit. During development of an Emergency Action Plan, personnel must identify fire extinguisher locations and determine if available extinguishers are appropriate for planned shop activities. Ensure that fire extinguisher locations are marked with a red/white “fire extinguisher” sign posted at eye level above the device. Monthly fire extinguisher inspections are required. Annual extinguisher testing is performed by EH&S. Fire Safety and Extinguisher Training is required for all shop personnel. It is recommended that personnel take the hands-on training, if it is their first time completing the training. Additional information is contained in the university’s Fire Safety Guidelines. First Aid Kits A properly stocked first aid kit shall be available to shop personnel. Complete kits are available at Central Stores (515) 294-0408 or through CyBuy. A list of recommended contents can be found in the Iowa State University First Aid Guidelines. Signs to mark the location of the first aid kit are available from EH&S. Flammable Safety Cabinets Flammable safety cabinets are storage cabinets (typically metal) manufactured to isolate flammable materials from a potential fire that may occur in the shop. Safety cabinets are required for storage of flammable liquids in shop with cumulative quantities greater than 40 liters (~10 gal.) and are available for purchase through safety equipment suppliers.

21 Shop Safety Flammable Safety Cans Flammable safety cans are containers (typically metal) with selfclosing spouts and integral flame arresters used to store flammable liquids for quantities greater than four liters (~1 gal.). Safety cans must be properly labeled and are available for purchase through safety equipment suppliers. Refer to flammables in Section G, “Safety Practices for Specific Hazards” for more information. Personal Protective Equipment (PPE) Minimum personal protective equipment (PPE) requirements for entering a shop will be posted at the door on the Safety Rules poster. Any PPE required above the minimum will be determined through completion of a job hazard assessment or development of a standard operating procedure (SOP). PPE should be included in the SOP for the process. Shop users are expected to use assigned PPE when called for by the hazard assessment, standard operating procedure, container label or safety data sheet. PPE shall be maintained by the user in a clean, sanitary and usable condition. PPE is available for purchase at Central Stores, 195 General Services Building (515) 294-0408 or Chemistry Stores, 1351 Gilman Hall (515) 294-0203. Soiled PPE should NEVER be taken home for laundering. Specific information on PPE requirements is available in the ISU Personal Protective Equipment Policy. Safety Shower An easily accessible, drench-type safety shower shall be available within ten seconds travel time of each area where corrosive or toxic liquids are used or stored. In some buildings, shops may need to rely on safety showers outside the shop. During development of an Emergency Action Plan, personnel must identify safety shower locations and verify proper function by contacting the building area mechanic. Ensure that safety shower locations are marked with a sign (typically green/white, available from EH&S) posted at eye level below the shower. Annual safety shower testing is performed by Facilities Planning and Management (FP&M). Spill Kits Aproperly stocked spill control kit shall be available in each shop. Spill kits are available at Central Stores, or safety equipment suppliers. In lieu of purchasing a kit, personnel may choose to assemble a kit. Instructions are available here.

22 Shop Safety H. Exposure Assessment and Medical Care Exposure assessment and medical care must be considered when developing shop procedures. Certain chemical, biological, radiological, and physical hazards require specific health monitoring. It is the responsibility of the PI, shop supervisor and department to ensure personnel are receiving appropriate monitoring and/or medical care based on shop hazards. Medical Emergencies If injury, illness, or exposure is life threatening, dial 911. Be prepared to provide any relevant safety information, such as an SDS. When an employee requires emergency treatment, the incident must be reported to EH&S (515) 294-5359 as soon as possible. Provide assistance to injured or exposed personnel by following the First Aid Procedures. Occupational Medicine Program The Iowa State University Occupational Medicine Program is designed to minimize personnel health risks from workplace hazards. Hazards may include chemicals such as formaldehyde or benzene; physical hazards such as excessive noise or lasers; human pathogens, tissues and cell lines; animal handling, pathogens, tissues and cell lines; and radioactive materials or devices. The program includes workplace exposure assessments, exposure monitoring and medical surveillance. All Iowa State University personnel, including part-time and student workers, are encouraged to participate in the Occupational Medicine Program, which is provided at no charge. Refer to the Occupational Medicine Guidelines for more information. Workplace Exposure Assessment Participation in the Occupational Medicine Program requires completion of a Hazard Inventory form. The online form must be completed by new employees who are exposed to hazards as part of their assigned job duties and/or current employees who have changes to their hazards or personnel information. EH&S will use this information to determine the need for enrollment in the ISU Occupational Medicine Program. Individuals and supervisors will receive an email after EH&S has completed the evaluation of the hazards, and can login to see the results. If it is determined that the individual’s workplace hazards require medical monitoring or training, the individual will receive a notice from the ISUOccupational Medicine Program with further instructions.

23 Shop Safety Exposure Monitoring As part of the workplace exposure assessment, exposure monitoring may be performed by EH&S to quantify the level of exposure experienced by employees at Iowa State University. Monitoring results are used to determine if medical surveillance is required and whether control measures should be implemented to ensure a safe work environment. Each department and supervisor is responsible for ensuring that any recommended control measures are implemented. EH&S may perform additional monitoring to determine the effectiveness of control measures. EH&S is available to conduct occupational exposure monitoring whenever a possible exposure or potential health hazard is suspected in the work environment. Medical Surveillance Employees enrolled in the Occupational Medicine Program will be required to complete a baseline medical review at the Occupational Medicine office, G11 Technical and Administrative Services Facility (TASF), 2408 Pammel Drive, (515) 294-2056. The Occupational Medicine physician will determine what tests and immunizations will be required to prevent occupational disease relating to an employee’s exposure. Ongoing medical surveillance will be offered to personnel exposed to hazards covered under OSHA or other applicable regulations. A separation medical review will be offered to Occupational Medicine Program participants when leaving ISU. Work-Related Injuries, Illnesses, and Exposures Iowa State University employees exposed or injured while at work or in the course of employment must seek medical attention at the McFarland Clinic PC, Occupational Medicine Department, 1215 Duff Ave, Ames, IA; (515) 239-4496. Supervisors should call the McFarland Clinic Occupational Medicine Department during regular work hours to schedule an appointment for the employee. Any relevant safety information such as an SDS should accompany the employee to the appointment. Reporting All work related injuries, illnesses, or exposures must be reported to the employee’s supervisor, even when medical attention is not required or is refused by the employee: An Incident Report (IR) must be completed by the injured employee and/or the supervisor through the ISU Incident Portal within 24 hours of the incident. Upon submission of the report, the supervisor will receive an email requesting information relating to the Accident Investigation as part of the incident reporting process. The supervisor is asked to reply directly to the email with answers to the questions asked within 24 hours of receiving the email. Questions regarding Some of the evaluations EH&S can perform include: • ergonomics • indoor air quality • noise • dust • mold • hazardous chemicals • physical hazards
