The document outlines key laboratory safety procedures and guidelines. It discusses health hazards of chemicals including routes of entry and toxic effects. It also covers laser safety, first aid, and general lab safety rules that must be followed, emphasizing that safety is the top priority in the lab. Risk of chemical exposure depends on toxicity and exposure level. Effects may be local or systemic, acute or chronic. All lab users must understand laser safety signs to avoid eye and skin injuries. Proper safety equipment, posters, and trained first aid are necessary to ensure a safe lab environment.

14. Safety is our FIRST priority Be Laser Safe! High-power lasers are in use in many research labs and are fundamental to making many of today's scientific discoveries. Every employee should know the meaning of laser safety signs to prevent inadvertent injury from entering a laser use area.

15. Safety is our FIRST priority Danger! Very high-power lasers may be in use. Even momentary exposures may cause burns or permanent eye damage. Do not enter unless authorized to do so.

16. Safety is our FIRST priority Caution! High power lasers may be in use. Extended exposures may damage the eyes. Do not enter unless authorized to do so.

17. Safety is our FIRST priority Notice! Laser installation, repair, set-up, or modification is in progress. Do not enter.
