Hierarchy Of Controls
Controlling exposures to occupational hazards is the fundamental method of protecting workers. Traditionally, a hierarchy of controls has been used as a means of determining how to implement feasible and effective controls. One representation of this hierarchy can be summarized as follows:
Personal protective equipment
a particulate collection device that removes particles from a flowing gas (such as air) using the force of an induced electrostatic charge. Electrostatic precipitators are highly efficient filtration devices that minimally impede the flow of gases through the device, and can easily remove fine particulate matter such as dust and smoke from the air stream.
Class E Helmet
are intended to reduce the force of impact of falling objects and to reduce the danger of contact with exposed high-voltage electrical conductors. Sample shells are proof-tested at 20,000 volts.
Class G Helmet
are intended to reduce the force of impact of falling objects and to reduce the danger of contact with exposed low-voltage electrical conductors. For certification, sample shells are proof-tested at 2,200 volts of electrical charge.
Class C Helmet
are intended to reduce the force of impact of falling objects, but offer no electrical protection.
chemicals that will irritate various tissues causing redness, rashes, swelling, coughing, or even hemorrhagging.
cause alterations in the genes of a person

The visible spectrum is the portion of the electromagnetic spectrum that is visible to (can be detected by) the human eye.
. Electromagnetic radiation in this range of wavelengths is called visible light or simply light. A typical human eye will respond to wavelengths from about 390 to 750 nm
is a toxic chemical substance which damages the liver.
is a poisonous effect of some substances, both toxic chemicals and medication, on the kidneys.
are toxin s that destroy red blood cell s
Chemicals that cause instant tearing
An effect in which two substances or actions used in combination produce a total effect the same as the sum of the individual effects.
It is not uncommon for the effect of two chemicals on an organism to be greater than the effect of each chemical individually, or the sum of the individual effects. The presence of one chemical enhances the effects of the second. This is called a synergistic effect or synergy, and the chemicals are sometimes described as showing synergism.
The action of a substance, at a dose that does not itself have an adverse action, in enhancing the effect of another substance
where the involvement of multiple agents reduces their overall effect
