                                    SAFETY RULES AND REGULATIONS

SAFETY TOOLS

• Wear eye protection at all times in the laboratory.

• Shoes must completely cover the foot. No sandals are allowed.

• Dress properly during all laboratory activities. Long hair, dangling jewellery, and loose or baggy clothing are a hazard in the laboratory. Long hair must be tied back and dangling jewellery and loose or baggy clothing must be secured.

• Never work in the laboratory alone, always have another qualified person in the area

• Wearing an "IPod" or other device that interferes with hearing is not allowed.

• Do not use any equipment unless you are trained and approved as a user by your instructor or staff. Ask questions if you are unsure of how to operate something.

• Perform only those experiments authorized by the instructor. Never do anything in the laboratory that is not called for in the laboratory procedures or by your instructor. Carefully follow all instructions, both written and oral. Unauthorized experiments are prohibited.

• Don't eat, drink, or smoke, in the laboratory

• Please don’t yell, scream, or make any sudden loud noises that could startle others who are concentrating on their work.

• If any laboratory equipment is malfunctioning, making strange noises, sparking, smoking, or smells "funny,” Get an instructor or staff immediately. It is imperative that the instructor or staff knows of any equipment problems.

• All accidents, no matter how minor, should be reported to the faculty/staff member supervising the laboratory immediately.

  Keep aisles clear and maintain unobstructed access to all exits, fire extinguishers, electrical panels, emergency showers, and eyewashes.

• Do not use corridors for storage or work areas.

• Avoid using extension cords whenever possible. Extension cords should not go under doors, across aisles, be hung from the ceiling, or plugged into other extension cords.

• When using compressed air, use only approved nozzles and never direct the air towards any person.

• Guards on machinery must be in place during operation.

• Exercise care when working with or near hydraulically- or pneumatically-driven equipment. Sudden or unexpected motion can inflict serious injury.
