The National Fire Protection Assn. has revised the guidelines for safety requirements for school laboratories. 

Teachers performing demonstrations or experiments are required to 

• perform a documented hazard risk assessment, 

• provide a safety review to students, 

• provide adequate personal protective equipment, and 

• place a safety barrier between students and the demonstration or experiment to prevent personal injury.
