33 X-Ray Safety Alarm System Activation The locations of alarm pull stations can be found on the building emergency map (fire alarm, chemical spill, severe weather). Laboratory employees must know how and when to activate alarms. Evacuation Procedures Identify evacuation routes and meeting locations for emergencies such as fire, severeweather, and chemical, biological, or radiological releases. Building Emergency Maps are available for download on the EH&S website. Fire Emergencies For all fires, activate alarm, dial 911, and evacuate. Additional information is contained in the Evacuation Procedures web page and the Fire Safety Guidelines . Spill/Release Containment and Cleanup Methods Develop cleanup/response procedures for the chemical, biological, and radiological materials used in the laboratory. Incorporate any specialized neutralization and decontamination methods for the materials used (biohazardous materials, hydrofluoric acid, etc.). These procedures should be part of the Emergency Action Plan and the laboratory standard operating procedure. The following generic spill/release procedures have been developed to provide a basis for laboratory-specific methods. • Chemical Releases to the Environment • Chemical Spill - Small • Chemical Spill - Large • Compressed Gas Leak Procedure • Mercury Spills Intruders An intruder is any unauthorized person who makes inappropriate or unwanted entry into the laboratory. Establish a protocol for responding to a laboratory intruder. The following steps should be included in the protocol for responding to an intruder: • require all unknown laboratory entrants to identify themselves and their purpose • report all laboratory intruders by dialing 911 • do not attempt to detain the intruder
