Effective Engineering Control

Wood preservatives that contain creosote, pentachlorophenol, inorganic arsenic, and chromates are widely used.

Because these chemicals are carcinogens, exposures to employees must be eliminated or reduced to the lowest levels possible below the Permissible Exposure Limits (PELs) by using effective engineering control (for example, enclosure or confinement of the operation, general and local exhaust ventilation, and substitution of less toxic materials).

When effective engineering controls are not feasible, or while they are being instituted, use of National Institute for Occupational Safety and Health (NIOSH) approved respirators is required to eliminate harmful airborne exposures to these chemicals. 5141, 5144(a), 5214

Protective Clothing and Equipment

When the probability of skin or eye irritation exists, workers must use appropriate protective clothing and equipment, such as coveralls, gloves, shoes, face shields, or impervious clothing.
