This document provides information on personal protective equipment (PPE) for chemical protection. It discusses both active protection gear like acid and alkali resistant body suits, and passive protection gear such as safety signs, fire extinguishers, chemical labeling, and first aid kits. The document explains that active gear provides direct protection from chemicals through materials like PVC fabric, while passive gear prevents accidents through indicators and aids treatment through signs and emergency equipment. Selection of protective materials depends on factors like permeation rate, breakthrough time and degradation from chemical exposure. Proper maintenance of passive gear like fire extinguishers and routine checks of first aid kits are also covered.

2. Personal Protection Equipment (PPE) for Chemical type protection
ACTIVE Protection Gear/Equipment
Acid and Alkali resistant body suit
Mainly suitable for firefighters protective clothing in the places of hazardous chemicals,
corrosive substances, and toxic gas accident. The garment full used of PVC fabric material,
which with double-sided strong acid and alkali responding performance. Can effectively
resistant the danger of aromatic hydrocarbon and homogenate, acid, vegetable oil and
animal fats. Full dress was double sewed, and double-sided hot connections, without
apparent juncture, zipper is completely closed. It cans built-in air respirator and wireless
communication system. It is in line with the standards both of GA 6-2004 "firefighters
extinguishing protective boot and Q/XFZB004-2006 the firefighters chemical protective
Clothing”
- Chemical (acid/alkali) resistance
- Water proof
- May request for tailored made fire proof protection gear.
- Usually comes in bright color garment (orange, yellow, red, light green), for easy spot

3. ACTIVE Protection Gear/Equipment
1. Permeation rate:
The rate at which the chemical will move through the material. Measured in the lab &
usually is expressed in unit mg/m2*second. Is not the same like penetration. Higher
Permeation rate, higher the chemical move through the material.
2. Breakthrough time:
The time needed for a certain chemical species to permeate completely through the material.
Breakthrough time gives rough estimation on how long a glove/suit can be used before
Chemical permeate through.
3. Degradation:
Is measured due to constant exposure to chemical leading to material degradation. Material
Will get harder, stiffer, brittle, softer and worse dissolve in chemical.
Hazard coverall
• Normally, resistance to strong acid/alkali and well equipped with breathing system.
• Water and Gas resistance is a standard features, but may request for special operation
e.g. radiation resistance (different material).
Factors in determining material for glove, suits and safety shoes

4. A B
Breathing Apparel Respirator with changeable filter
A & B :
Specific type of mask usually used for
Specific job task or application e.g. Fire Fighter
who deals with gas/ poisonous vapor adopt
for A type mask.
B type mask is usually worn by chemist, or
any personal to avoid strong smell and ultra fine
Particles in air. B type deals with vapor but not
as lethal as A type mask which need separate
oxygen supply.
C D
ACTIVE Protection Gear/Equipment
C & D:
Replaceable filter 1 time used
C type mask usually used for common household chores. Normally used
to prevent dusk & debris from lung system. Offer minimal protection.
D type is 1 time used mask. Disposable upon used. Is categorized
by size of debris is filter PM10 and PM2.5. PM10 is 10 micron size
Debris, while PM2.5 is from > 2.5 micron debris. Usually PM 10
Used for haze/fog.

5. Personal Protection Equipment (PPE) for Chemical type protection
PASSIVE Protection Gear/Equipment
Safety Sign/ indicator
 As the first line defense for preventive action.
 Plant personnel must brief each of the visitor on the meaning of each sign.

6. • In the case of accident involving strong chemicals
Acid/alkali:
I. Wash eyes thoroughly using the eyes washer (minor
spills) – if U accidently sprinkle chemicals in your eyes.
2. If U accidently spill some strong acid/alkali on you hand,
Immediately run the spilled area (your hand) under
running water. After awhile, normal soup can be use to
neutralize the acidity. If it’s a strong alkali, wash your hand
under running water for awhile, and apply mild vinegar
or any weak acid based e.g. acetic acid, etc. Both strong
acid & alkali gives heat sensation & irritate on the skin.
3. If major spills (involving strong acid/alkali ), remove
your clothes (affected area) and immediately take
bath using the appropriate equipment (washer). Report
the incident to your supervisor for further action.

7. Fire Extinguisher
PASSIVE Protection Gear/Equipment
Types & Use:
(UK standard)
Class A: SOLIDS such as paper, wood, plastic etc.
Class B: FLAMMABLE LIQUIDS such as paraffin,
oil, etc.
Class C: FLAMMABLE GASES such as propane,
butane, methane, pentane etc.
Class D: METALS such as aluminium, magnesium,
titanium, etc.
Class E : Fires involving ELECTRICAL APPARATUS
Class F : Cooking Oil and FAT etc.

8. PASSIVE Protection Gear/Equipment Fire Extinguisher (UK standard)
Maintenance: 3 types of maintenance
1. Basic service: Check weight, correct pressure (using special tools) and for sign of damage or corrosion,
cartridge extinguishers are opened up for internal inspection & check weighting of the cartridge, labels are
checked for legibility, where possible dip tubes, hoses and mechanism checked for clear free operation.
2. Extended Service: Water, Wet Chemical, Foam & Powder extinguishers require every five years a more
detailed examination including a test discharge of the extinguisher and recharging; on stored pressure
extinguishers this is the only opportunity to internally inspect for damage/ corrosion. By recharging fresh agent
is used as they all have a shelf life, even water goes foul inside the extinguisher.
3. Overhaul: CO2 extinguishers, due to their high operating pressure, are subject to pressure vessel safety
legislation and must be hydraulic pressure tested, inspected internally & externally and date stamped every 10
years. A new valve is also fitted as it cannot be pressure tested. Cannot use parts from different manufacturer
as it will invalidate fire rating.

9. PASSIVE Protection Gear/Equipment
Chemical ‘Birth Certificate’
Proper labelling & Handling

10. PASSIVE Protection Gear/Equipment
First aid kit
- Contain basic equipment for 1st aider prior to appropriate
medication/help
- Periodical check is necessary (max is 6 month routine)
- Placement is very crucial for easy access
