A known contaminant at a concentration known to be IDLH.There are particular conditions that are considered 'Immediately Dangerous to Life or Health (IDLH)'. Some types of atmospheres contain concentrations of hazardous substances that places the worker in immediate danger because these concentrations would impair the ability to leave the work area (self rescue) or potentially cause irreversible health effects, including serious injury or death in a matter of minutes. Administrative controls are not generally favoured because they can be difficult to implement, maintain and are not reliable.

These control measures have many limitations because the hazard is not removed. Administrative controls limit workers' exposures by scheduling reduced work times in contaminant areas or by implementing other such work rules. process modifications including substitution of less hazardous materials where possible.Īdministrative controls may be used in addition to engineering controls.proper control and use of process equipment, and.enclosure or isolation of the process or work equipment.A written workplace hazard control program should outline which methods are being used to control the exposure and how these controls will be monitored for effectiveness.Īfter elimination and substitution, well designed and maintained engineering controls are the preferred methods of controlling worker exposure to hazardous contaminants in the air. Note that more than one respiratory hazard can be present at the same time.Ī hazard control program consists of all steps necessary to protect workers from exposure to a substance or system, the training and the procedures required to monitor worker exposure and their health to hazards such as chemicals, materials or substance, or other types of hazards such as noise and vibration. Respiratory hazards can include airborne contaminants such as biological contaminants, dusts, mists, fumes, and gases, or oxygen-deficient atmospheres.
