OVERVIEW OF THE PRESENTATION
INTRODUCTION.
CHEMICAL & BIOLOGICAL AGENTS.
MATERIALS USED IN CB SUITS
CLASSIFICATION OF CB SUITS
CB PROTECTIVE CLOTHING.
TESTING & EVALUATION OF THE SUITS
ADVANTAGES AND DRAWBACKS.
CONCLUSION.
chemical and biological protective clothing
This is basically used in military and in chemical industries.
It acts a barrier between us and the chemical and biological agents.
The protective clothing consists of three layers outer fabric, sportive layer and inner layer.
FUNCTIONS OF THE 3 LAYERS
The outer shell is a water repellent layer protecting from liquid chemicals.
The sportive layer is the soul of the protective clothing absorbing liquid and air borne chemicals.
The inner layer provides comfort to the wearer.
MATERIALS FOR CB PROTECTIVE CLOTHING'S
There are basically four different types of CB Protective Materials.
Air-permeable materials
Semi permeable materials
Impermeable materials
Selectively permeable materials (SPMs)
CB PROTECTIVE SUIT WITH ITS COMPONENTS
Wet-Weather Gear.
Biological and Chemical Bag.
Self-Contained, Toxic-Environment Protective Outfit.
Chemical Protective Glove Set.
Green Vinyl Overshoe, Black Vinyl Overshoe, and Multipurpose Lightweight Over boot.
A/P22P-9A (V) Below-the-Neck Protective Assembly.
BC Protective Cover.
WET WEAR GARMENT
provides initial protection against CB agents.
It is made of green,
chloroprene-coated nylon.
The jacket style parka has :
slide fastener with moisture barrier flaps,
patch pockets,
permanently attached hood.
GREEN VINYL OVERSHOE, BLACK VINYL OVERSHOE
Worn over standard combat boots to provide chemical/biological and wet weather protection.
Attributes:
Material : poly vinyl chloride
24 hour protection
14 day field wear
BIOLOGICAL AND CHEMICAL BAG
The CB equipment protective bag is constructed of abrasion-resistant nylon and is designed to consolidate and transport the decontamination kits.
The bag comes in one size and has a four-color, woodland camouflage pattern.
CHEMICAL PROTECTIVE GLOVE SET
Worn under standard issue hand wear
ATTRIBUTES
25 mil. (0.025 inch thick) butyl rubber glove and cotton inner glove
24 hour protection
14 day field wear
