    Where risk assessment shows air-purifying respirators are appropriate use a full-face particle
    respirator type N100 (US) or type P3 (EN 143) respirator cartridges as a backup to engineering
    controls. If the respirator is the sole means of protection, use a full-face supplied air respirator. Use
    respirators and components tested and approved under appropriate government standards such
    as NIOSH (US) or CEN (EU).
