Are masks useful for reducing exposure to dust and smoke?
Use of protective dust masks and dust-filtering respirators can effectively remove dust from inhaled air. For those working in dusty areas, exposure can be reduced by wearing well-fitted dust masks (such as N-95 or more protective NIOSH-approved respirators available commercially.) A poor fit can allow dust to bypass the dust filter, sharply reducing the effectiveness of the mask. These dust-filtering masks are only effective against dust and provide no protection against toxic fumes or suffocation from lack of air. Firefighters and other emergency responders with potential for intense exposures often need air-supplied respirators for such special situations. What are other protective measures? • Protect eyes by wearing appropriate goggles. • Protect skin by wearing gloves, shoes and clothing designed to keep the dust away. • Wash face and hands often and always before eating and drinking. • Try to keep dust that settles on clothing away from areas without dust • Rinse hair, hands and
