Levels of Protection There are four (4) levels of chemical protection. Level A - Highest level of respiratory and skin protection. Level B - Lesser degree of skin protection, highest level of respiratory protection. Level C - Lesser degree of skin protection, lesser degree of respiratory protection (APR). Level D - Work/ Utility, coverall. LEVEL A Vapor & gas tight design - The highest level of respiratory protection and skin protection. LEVEL B Level B Protection is used when a lesser degree of skin protection is required but the highest level of respiratory protection is still needed. LEVEL C Is Used when a lesser degree of skin protection and respiratory protection is needed. An Air Purifying Respirator (APR) can be used only when the product is known, there is sufficient oxygen in the air, and the appropriate filter is available. Level D Work utility uniform. Provides a barrier to dusts, mist and powder type hazards. It provides some protection from physical hazards. It is considered as a work uniform and not used on any site with respiratory or skin absorption hazards. Fire Fighter s LEVEL D Work utility uniform. Provides a barrier to dusts, mist and powder type hazards. Is considered as a work uniform and not used on any site with respiratory or skin hazard. A cotton or fire retardant (FR) coverall; with escape pak may also be used in place of structural firefighter equipment. Haz. Mat Operations Module 4 PPE 2

Selection of Levels of Protection CThe level of protection selected should be based on: CThe type and measured concentration of the chemical substances in the ambient atmosphere and its toxicity. CPotential for exposure to substances in air, splashes of liquids, or other direct or in direct contact with materials or substances. C Type of work being performed or expected. CIn dealing with unknown concentrations or levels of exposure, the maximum level of protection should be selected. Levels of Protection Factors for consideration STRENGTH: The materials ability to resist tares, punctures, and abrasions as well as tensile strength. FLEXIBILITY: The ability of a material to remain soft and pliable, easy to move about and work. Stretchability. Levels of Protection Factors for consideration Levels of Protection Factors for consideration THERMAL LIMITS: The ability of a material to maintain its protective capability in temperature extremes. Thermal limits would include cold weather and hot weather. Examples would be that of how lower temperatures effect mobility and how during high temperature the material insulates the wearer. LIFE EXPECTANCY: The ability to resist aging due to exposure to sunlight, general use, repeated washing using cleaning agents and its ability to be decontaminated. Routes of Entry Routes of Entry/Effects of Exposure Routes of Entry Materials have the ability to enter into our body several ways. INHALATION INGESTION ABSORPTION INJECTION ACUTE High Dose over short time Usually recover quickly. hang-over, drunkenness, vomiting, unconsciousness CHRONIC Small Dose over long period of time liver damage cirrhosis, addiction,alcoholism, death.

CHEMICAL RESISTANCE The ability of a material to physically resist being degraded, penetrated and or permeated by exposure or contact with a chemical. Basic Terms DEGRADATION PENETRATION PERMEATION DEGRADATION: Degradation is the loss in physical properties caused by an exposure to a chemical(s). Damage to the material may be so slight that it may not be visible to the naked eye to detect deterioration of the material. PERMEATION: Is the process by which a chemical moves through a material on a molecular level or diffusion. Permeation is typically measured by the time it takes to pass from the outside of a material (once exposed) and be measured on the inside. This is referred to as permeation time. Permeation rate is the rate or amount at which the chemical passes through. It is important to note that not all substances permeate all materials. PENETRATION: Is the flow of a substance or material through openings such as zippers, seam, stitches, holes or tears in the garment.

DUCT TAPE Duct tape has been in use for many years. While there has not been any definitive testing of the flammability, combustibility, chemical resistance or chemical compatibility of duct tape, there is controversy between Hazmat Teams and response specialists on it s use.
