What are the 4 engineering controls?

Traditionally, a hierarchy of controls has been used as a means of determining how to implement feasible and effective controls, which typically include elimination, substitution, engineering controls, administrative controls, and personal protective equipment.

What are engineering controls in safety?

Engineering controls protect workers by removing hazardous conditions or by placing a barrier between the worker and the hazard. Examples include local exhaust ventilation to capture and remove airborne emissions or machine guards to shield the worker.

What are the three types of engineering controls?

Engineering controls consist of a variety of methods for minimizing hazards, including process control, enclosure and isolation, and ventilation.

Is PPE considered an engineering control?

According to the Centers for Disease Control and Prevention (CDC), PPE is used by 20 million workers and is very important, but according to OSHA it must be considered last after all engineering and administrative/work practice controls.

What is the science behind engineering controls?

The basic concept behind engineering controls is that, to the extent feasible, the work environment and the job itself should be designed to eliminate hazards or reduce exposure to hazards. …

Is PPE an engineering control?

Engineering controls are favored over administrative and personal protective equipment (PPE) for controlling existing worker exposures in the workplace because they are designed to remove the hazard at the source, before it comes in contact with the worker.

Are gloves an engineering control?

Environmental Health & Safety The next few pages deal primarily with “engineering controls”, i.e. fume hoods, gas cabinets, glove boxes, etc. Engineering controls are considered the “first line of defense” in protecting workers.

What are the most effective hazard controls?

Elimination. Physical removal of the hazard is the most effective hazard control. For example, if employees must work high above the ground, the hazard can be eliminated by moving the piece they are working on to ground level to eliminate the need to work at heights.

How are engineering controls used to protect workers?

Well-designed engineering controls can be highly effective in protecting workers and will typically be independent of worker interactions to provide this high level of protection.

How are engineering controls used in psychosocial hazards?

Psychosocial hazards. Engineering controls for psychosocial hazards include workplace design to affect the amount, type, and level of personal control of work, as well as access controls and alarms. The risk of workplace violence can be reduced through physical design of the workplace or by cameras.

Where can I find information on engineering controls?

For descriptions of engineering control technologies researched by NIOSH, and information on the control details and their effectiveness, visit our Engineering Controls Database. The engineering controls contained in the database are beneficial for users who need control solutions to reduce or eliminate worker exposures.

Which is higher engineering controls or administrative controls?

The initial cost of engineering controls can be higher than the cost of administrative controls or PPE, but over the longer term, operating costs are frequently lower, and in some instances, can provide a cost savings in other areas of the process.
