1. CHEMICAL PROTECTIVE CLOTHING

2. CHEMICAL PROTECTIVE CLOTHING
Purpose:
Shield or isolate individuals from the chemical, physical, and biological hazards that may be encountered during hazardous materials operations
Not always apparent when exposure occurs.
Many chemicals pose invisible hazards and offer no warning properties.
No single combination of protective equipment and clothing is capable of protecting against all hazards.

3. CHEMICAL PROTECTIVE CLOTHING
Protective clothing should be used in conjunction with other protective methods:
Engineering or administrative controls to limit chemical contact (prevention)
The use of protective clothing can itself create significant wearer hazards, such as heat stress, physical and psychological stress, in addition to impaired vision, mobility, and communication.
In general, the greater the level of chemical protective clothing, the greater the associated risks.
For any given situation, equipment and clothing should be selected that provide an adequate level of protection.
Overprotection as well as under-protection can be hazardous and should be avoided.

4. CHEMICAL PROTECTIVE CLOTHING
Protective clothing must be worn whenever the wearer faces potential hazards arising from chemical exposure. Some examples include:
Chemical sampling / monitoring
Emergency response
Fire
Overflow / Spill
Leakage
Rescue
Decontamination

5. CHEMICAL PROTECTIVE CLOTHING
Intergration clothing and equipment
Task performance is necessary
Ensemble may include:
Protective clothing (suit, coveralls, hoods, gloves, boots)
Respiratory equipment (SCBA, combination SCBA/SAR, air purifying respirators)
Cooling system (ice vest, air circulation, water circulation)
Communications device
Head protection
Eye protection
Ear protection
Inner garment
Outer protection (overgloves, overboots, flashcover).

6. VAPOUR PROTECTIVE SUIT
Pressure-demand, full-face SCBA, inner chemical-resistant gloves, chemical-resistant safety boots, two-way radio communication
Highest available level of respiratory, skin, and eye protection from solid, liquid and gaseous chemicals.
High level of hazards to respiratory system, skin and eyes.
Substances are present with known or suspected skin toxicity or carcinogenity.
Operations conducted in confined or poorly ventilated areas.
Ensemble items must allow integration without loss of performance.

13. DECONTAMINATION

14. DOFFING SUIT With subject standing, unzip the suit completely.
From the rear, place a gloved hand on the back of the subject’s head and invert the hood.
From the front, roll the suit down over the shoulders. (turning it entirely inside out)
Pull arms out
Once the knees are clear the subject may sit down.
Complete rolling suit down over the boots. pull the boots off using the inverted suit.  
Subject removes the mask

15. LIQUID SPLASH PROTECTIVE SUIT
Provides same level of respiratory protection but less skin protection. Liquid splash protection, but no protection against vapours or gases
Chemicals do not require a high level of skin protection.
Primary hazards are associated with liquid contact, not with vapour
Intergration without loss of performance must be possible

16. LIQUID SPLASH PROTECTIVE SUIT

17. SUPPORT FUNCTION PROTECTIVE GARNMENT
Same level of skin protection, but lower level of respiratory protection.
Protection against liquids, not against vapours or gases
Hazards have been completely identified
Chemical concentrations must be under TLV and O2 content above 19.5%
