Personal Protection: Masks, Safety Glasses & Respiratory Protection
AI Summary: Respiratory and eye/face protection should be selected according to dust, fume, chemical splash, noise and infection risks. Ordinary dust masks, particulate respirators and chemical respiratory protection must not be used interchangeably; safety glasses must resist splashes and be compatible with prescription glasses and safety helmets. Improper selection gives users a false sense of safety.
