1.3.1 Respiratory Protection There are two basic classes of respiratory protection. These are the filter type and the supplied air type. Within these two basic groups there are many variations. We will be discussing two kinds of filter respirator (half mask and full-face piece) in addition to the self-contained breathing apparatus which is a supplied air unit. 1.3.1.1 Half Mask Respirators A half mask respirator has a face piece that covers the wearer's nose, mouth and chin and is fitted with one or two air purifying canisters that use a filter, sorbent or combination of both to remove airborne contaminants from otherwise breathable air. These units have the advantage of being small, light, simple to use and quick to put on. They are also very limited in scope and range and must not be used in atmospheres immediately dangerous to life or health (IDLH). The following requirements must be observed when using half mask respirators: Use only when the contaminant and maximum concentration is known. There must be SUFFICIENT OXYGEN to support life (20.9%). .
This information may be required in other aspects of your work, such as in the preparation of a hazardous materials sample for shipment or transportation. Once you determine the level of intervention required by your job assignment, the SDS is to be reviewed before you do anything else.
Section 9: Physical and chemical properties Provides additional data that can be used to help characterize the material and design safe work practices. Section 10: Stability and reactivity Describes the conditions to be avoided or other materials that may cause a reaction that would change the intrinsic stability of the material. 1.2.4 Is There Any Other Useful Information About This Material? The following information in sections (11-16) may not always apply in all countries but is usually provided.
1.3 Personal Protective Equipment
All petroleum products are hazardous and toxic. They can be handled safely if a level of care appropriate to their potential harm is exercised. The purpose of personal protective equipment is to prevent a hazardous material from coming into contact with the body.
Section 11: Toxicological information Section 12: Ecological information Section 13: Disposal considerations Section 14: Transport information Section 15: Regulatory information Section 16: Other information
The principal means of contact are: Direct contact to the skin or eyes. Inhalation of vapors or mists. Absorption through the skin.
The SDS is not simply another piece of paperwork that forms part of the overall job documentation. The SDS will tell you the level of respiratory protection you will need and what additional types of personal protective equipment could be needed.
