Filtering respirators

Two compounds associated with particular industrial risks are iron(III) oxide, Fe202, and iron pentacarbonyl, Fe(CO). Chronic inhalation of iron(III) oxide leads to siderosis. Adequate ventilation and mechanical filter respirators should be provided to those exposed to the oxide. Iron pentacarbonyl is volatile and highly toxic.

Do NOT wash away into sewer. Sweep spilled substance into containers if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Personal protection P3 filter respirator for toxic particles. Unbreakable packaging put breakable packaging into closed unbreakable container. Do not transport with food and feedstuffs.

Dust masks, or particulate filter respirators, protect the respiratory system against any kind of inhaled particles. The simplest type, in the form of a cone-shaped fibrous filter that fits over the nose and mouth, is held in place by an elastic band around the back of the head. It is disposable, relatively comfortable to wear, and is useful when the dust is neither excessive nor toxic. It becomes readily clogged and should be discarded and replaced whenever breathing becomes restricted. Its use should not be carried over from day to day.

PERSONAL PROTECTION Wear impervious protective clothing, including boots, chemical-resistant gloves, lab coat, apron or coveralls wear dust-proof safety goggles enclose operations and use local exhaust ventilation (not if powder) at site of chemical release use self-contained breathing apparatus for extra personal protection, use a P2 filter respirator for harmful particles. 

PERSONAL PROTECTION Wear full protective clothing, including rubber boots and heavy rubber gloves wear chemical safety spectacles, in combination with breathing protection enclose operations and use local exhaust ventilation at site of chemical release for extra personal protection, a P3 filter respirator for toxic particles is recommended. 

PERSONAL PROTECTION wear full protective clothing and chemical-resistant gloves wear chemical safety goggles wear self-contained breathing apparatus a closed system of local exhaust ventilation is recommended to control emissions at the source and to prevent dispersion into general work area use dust explosion-proof electrical equipment and lighting for extra personal protection, use a P2 filter respirator for harmful particles maintain eyewash baths and safety showers in work area. 

PERSONAL PROTECTION wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls use chemical safety goggles and/or full face shield where dusting or splashing of solutions is possible appropriate respirators with dust/mist filters are needed in areas where exposure would be above the permissible exposure level (PEL) use a full-facepiece positive pressure, self-contained breath apparatus in instances where the exposure levels are not known P2 filter respirators are recommended for harmful particles maintain eyewash fountains and quick-drench facilities in work area.
