A critical aspect of working safely with hazardous materials is the proper selection and use of personal protective equipment (PPE). All PPE should be carefully selected to ensure that it is appropriate for the hazards present and that the users will be able to perform their work in reasonable comfort wearing the protective equipment. Please contact Environmental Health & Safety at 8-8182 in the event of ANY questions regarding the proper selection of PPE for a given task.
Protective eyewear is required to be worn in any situation where there is a potential for damage to the eye. These situations include protection from flying debris, protection from chemical splashes, and protection from hazardous radiation such as lasers or ultraviolet light such as that often produced in welding operations. It is critical that the proper protective eyewear be selected for use.
Protective eyewear must offer appropriate protection from the hazards presented. For example, safety glasses do not offer sufficient protection from chemical splashes. Goggles or safety shields are indicated for that use. When dealing with chemical splashes, be sure the eyewear offers NO opportunity for chemical entry, such as often occurs with poorly placed ventilation holes.
In the case of protection from radiation, including and especially lasers, the eyewear must not only address the specific wavelength of the radiation but also offer sufficient protection from the power or intensity of the radiation.
Contact Environmental Health & Safety at 8-8182 for further assistance in selecting protective eyewear.
Protective gloves should be worn whenever there is the potential for skin damage or absorption through the skin when using a hazardous chemical. The gloves should be of a material appropriate for the chemical in question. Information as to appropriate materials is available in safety equipment catalogues from which gloves may be purchased. Care should be taken to ensure that the gloves fit properly ("one-size-fits-all" seldom does!) Also, an individual's susceptibility to latex allergies should be considered when selecting gloves.
Respirator use is strictly limited at Carnegie Mellon, permitted only for those approved for use by Environmental Health & Safety.
We strive to correct all potential exposure problems to hazardous materials by other means, without having to use respirators.
Refer to the Respiratory Protection Plan for further information.
