Cotton inserts are not adequate noise suppressors and should not be used. Hand Protection Protective gloves should be worn when handling hazardous chemicals, sharp-edged objects, very hot or cold materials, or substances of unknown toxicity. When selecting and using protective gloves, laboratory workers should take precaution. Protective gloves should be selected on the basis of the hazards involved. Polyvinyl gloves protect against mild corrosives and irritants.
Latex gloves have some protection against irritants and infectious agents.
Rubber gloves protect against mild corrosive material and electric shock. Neoprene gloves protect against solvents, oils, and mild corrosive material. Cotton gloves have limited protection against fire, and absorb perspiration. It is important to wear gloves that are resistant to the material being used. In an accident, the wrong type of glove can be more hazardous than no gloves at all, keeping hazardous chemicals in prolonged contact with the hands.
