The International Labor Organization, an organization of government, business, and labor groups that provides jobsite safety information, is another reliable source. Certain exposure conditions can be life-threatening. When available oxygen falls below 19.5 percent by volume, a potentially life-threatening deficiency can result. If these conditions exist, a safety professional should be consulted promptly. Respiratory protection distributors can help in the selection process.
Respirators come in many designs.
When spraying a paint containing solvents with good warning properties, an organic vapor chemical cartridge with a paint, lacquer, and enamel mist filter may be used. If the paint does not have good warning properties, an airline respirator may be used. OSHA standards prohibit wearing respirators when beards, facial hair, or other conditions that prevent a good seal between the face and respirator. Training should include basic procedures specific to each respirator, such as adjusting the head straps on elastomeric facepiece respirators to ensure a comfortable, secure fit. Fit tests must also be conducted to determine if the wearer can achieve a proper fit.
