Safe Work Practice(s)	Develop specific rules and procedures for all workers to follow when working in the presence of or potentially exposed to a hazard	Placing warning labels on hazardous chemicals
Administrative Control(s)	Developing other work practices to protect workers from hazards	Limiting the amount of time workers can work in a noisy area

15. What is the Hierarchy of controls?

                It’s important to work through a logical progression when you’re considering controls for a hazard. That logical progression, from first to last, is represented by the hierarchy of controls.

16.  Describe the examples of  Engineering control of Hazards?

Engineering controls are methods that are built into the design of a plant, equipment or process to minimize the hazard. The basic types of engineering controls are:

•Process control. (Process control involves changing the way a job activity or process is done to reduce the risk).

•Enclosure and/or isolation of emission source. (These methods aim to keep the chemical "in" and the worker "out" (or vice versa).An enclosure keeps a selected hazard "physically" away from the worker).

•Ventilation. (Ventilation is a method of control that strategically "adds" and "removes" air in the work environment).

.  Noise Exposure, . Flying debris Hazards, .Respiratory Hazard.

17.  What are the examples of Administrative control of Hazards?

 Administrative controls limit workers' exposures by scheduling shorter work times in contaminant areas or by implementing other "rules".

Work Practices , Education & Training, Good House Keeping.

When necessary, methods of administrative control include:

•Restricting access to a work area.

•Restricting the task to only those competent or qualified to perform the work.

•Scheduling maintenance and other high exposure operations for times when few workers are present (such as evenings, weekends).

•Using job-rotation schedules that limit the amount of time an individual worker is exposed to a substance.

18. What is the Role & Responsibilities of Fire Watch Man?
