Q: WHAT IS A HAZARDOUS MATERIAL ?A: Any substance which has the potential to cause harm or damage to people, property, or the environment. These substances can come in several forms.

SOLIDS

RAW SULPHUR

LIQUIDS

MDEA IN BARRELS

GAS OR VAPOR

May Be Invisible !

H2S GAS CLOUD

TYPES OF HAZARDS

THERE ARE 8 BASIC CLASSIFICATIONS OF HAZARDOUS MATERIALS

•COMPRESSED GAS

•FLAMMABLE OR COMBUSTIBLE MATERIALS

•OXIDIZING MATERIALS

•POISONOUS AND INFECTIOUS MATERIALS

•MATERIALS CAUSING IMMEDIATE & SERIOUS TOXIC EFFECTS

•MATERIALS CAUSING OTHER TOXIC EFFECTS

•CORROSIVE MATERIAL

•DANGEROUSLY REACTIVE MATERIAL

Chemical Handling

Plan - Work• Task : check the quality of NaOH before transferring it to

Unit 114 - Train 1

• Result : loss of sight ...

Chemical Handling

Anomalies...• Collect sample from drain line : access ? flow rate ?

• Use of plastic bottle ex. mineral water : spillage, resistant (chemical, heat), static electricity, mistaken as potable water

• No PPE

Chemical Handling

Chemical PPE (1)This is the minimumprotective clothing andequipment you shouldwear while dealing withchemicals which aremoderately to highly toxic

Face shield or goggles

Respirator (If the MSDSor label requires it)Protective suit (such as

fabric coveralls) wornover normal workclothes

Chemical-resistant apron

Chemical-resistant glovessuch as rubber, vinyl, orplastic.(Never use fabric, leatheror paper gloves)

Chemical-resistant bootsor footwear(Never wear leather orcanvas footwear)

Chemical Handling

Chemical PPE (2)

Protective suit (such asfabric coveralls) wornover normal workClothes

Chemical-resistant glovessuch as rubber, vinyl, orplastic.(Never use fabric, leatheror paper gloves)

Socks and shoes or boots

(Such as direct contact with spray, mist, or handling very highly toxic chemicals)

Diluted ChemicalsChemical-resistant hoodor hat

Goggles or face shield

Respirator (If the MSDS or label requires it or if mists, fogs, or vapors will be generated)

Chemical-resistant protective suit worn over normal work clothes(A chemical-resistant protective suit may cause heat stress under some conditions)

Chemical-resistant gloves such as rubber, vinyl, or plastic(Never use fabric, leather, or paper gloves)

Chemical-resistant bootsor footwear(Never wear leather or canvas footwear)

Physical Contacts : BodyIf any part of your body is in contact with corrosive chemicals (NaOH, H2SO4, HCl) go directly to the nearest safety shower and flush your body and clothes with large amounts of water.

Quickly remove all contaminated clothing including footwear.

Wash affected areas with water (and soap if available) for at least 15 minutes.

Seek medical attention immediately. REMEMBER 5555 ! Or EMERGENCY RADIO CHANNEL.

Again :Some chemicals are water reactive and become toxic

when mixed with water. IF IN DOUBT ASK

Chemical Handling

Physical Contacts… EyesJUST IN CASE :

you accidentally get something in your eyes, go directly to the nearest eyewash station (within 100 ft of your work area) and flush your eyes with water for 15 minutes.

Be sure to hold your eyes open with your fingers and “look” directly into the water streams. DO NOT RUB YOUR EYES !Rubbing your eyes may scratch or embed particles into your eyes.

Once you have flushed your eyes with water, seek medical attentionimmediately. REMEMBER 5555 ! Or EMERGENCY RADIO CHANNEL.

Some chemicals are water reactive and become toxic when mixed with water. Talk with your supervisor or HSE about the chemicals you will be using on your job. Be familiar with the MSDS for all chemicals used in your job.

Emergency shower with eyewash

Even a fire hydrant can be used to flush chemicals off of

a person

Before starting, find emergency water points

LIQUID SAMPLING

Use only approved sample bottles.

DO NOT USE WATER BOTTLES!!!
