Protective Equipment / Clothing

Red: Dust mask; gloves of rubber vinyl; chemical safety glasses; rubber shoes.

Yellow: ... Use flame-retardant clothing, gloves, face shields (eight-inch minimum), and any other appropriate protective clothing to prevent any possibility of skin contact ... . Use dust and splash-proof safety goggles .... Any clothing which becomes contaminated ... should be removed immediately ... .

Respiratory protection (supplied-air respirator with full facepiece or self-contained breathing apparatus) should be available where these compounds are manufactured or used and should be worn in case of emergency and overexposure. /Phosphorus compounds/

Wear appropriate personal protective clothing to prevent skin contact. [Note: Flame retardant personal protective equipment should be provided.]

Wear appropriate eye protection to prevent eye contact.

Eyewash fountains should be provided in areas where there is any possibility that workers could be exposed to the substance; this is irrespective of the recommendation involving the wearing of eye protection.

Facilities for quickly drenching the body should be provided within the immediate work area for emergency use where there is a possibility of exposure. [Note: It is intended that these facilities should provide a sufficient quantity or flow of water to quickly remove the substance from any body areas likely to be exposed. The actual determination of what constitutes an adequate quick drench facility depends on the specific circumstances. In certain instances, a deluge shower should be readily available, whereas in others, the availability of water from a sink or hose could be considered adequate.]
