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 Chemical Handling

TYPES OF HAZARDS
THERE ARE 8 BASIC CLASSIFICATIONS OF HAZARDOUS MATERIALS
Task : check the quality of NaOH before transferring it to Unit 114 - Train 1
Result : loss of sight ...
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
Chemical PPE (1) This is the minimum protective clothing and equipment you should wear while dealing with chemicals which are moderately to highly toxic Face shield or goggles Respirator (If the MSDS or label requires it) Protective suit (such as fabric coveralls) worn over normal work clothes Chemical-resistant apron Chemical-resistant gloves such as rubber, vinyl, or plastic. (Never use fabric, leather or paper gloves) Chemical-resistant boots or footwear (Never wear leather or canvas footwear) Chemical Handling
Chemical PPE (2) Protective suit (such as fabric coveralls) worn over normal work Clothes Chemical-resistant gloves such as rubber, vinyl, or plastic. (Never use fabric, leather or paper gloves) Socks and shoes or boots (Such as direct contact with spray, mist, or handling very highly toxic chemicals) Diluted Chemicals Chemical-resistant hood or 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 boots or footwear (Never wear leather or canvas footwear)
Physical Contacts : Body If 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… Eyes JUST 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 attention immediately. 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. Chemical Handling
FOR USE WHEN HANDLING CHEMICALS USE SAFETY GLASSES ONLY WHEN YOU WEAR A FULL FACE SHIELD Chemical Handling
Eyewash station What? Where? Eyewash Bottles Eyewash Station Emergency shower with eyewash Even a fire hydrant can be used to flush chemicals off of a person Before starting, find emergency water points Chemical Handling
LIQUID SAMPLING Use only approved sample bottles. DO NOT USE WATER BOTTLES!!! Chemical Handling
Valve A Valve B Gas Sampling for Double End Cylinders 20 Seconds Chemical Handling NEVER USE THE WORDS OVER AND OUT IT IS TOTALLY INCORRECT. Open ” Valve A” to flush sample point, for about 20 seconds. Close “Valve A”.
Valve A Valve B Gas Sampling for Double End Cylinders Chemical Handling Valve C Valve D Connect The top Valve “ VC” of the sample cylinder to the sample point using the sample connection line.
Valve A Valve B Gas Sampling for Double End Cylinders 20 Seconds Chemical Handling Open Valve “ A “ Open Valve “ B “ Open Valve “ A “ fully & open Valve “ B “ for 20 Seconds to flush the sample connection line. Close Valve “ B “. Close Valve “ B “ .
Gas Sampling for Double End Cylinders Valve A Valve B 2 Minutes Chemical Handling Open Valve “ C “ Open Valve “ D “ Open Valve “ C “ & then Valve “ D “ to purge gas down through the Cylinder for 2 minutes to remove all the air from the cylinder out.
Gas Sampling for Double End Cylinders Valve A Valve B Wait for 10 seconds Chemical Handling Close Valve “ D “ Close Valve “ C “ Close Valve “ A “ Close Valve “ D “ Wait for 10 Seconds then close Valve “ C “ followed by Valve “ A “.
Valve A Valve B Chemical Handling Gas Sampling for Double End Cylinders Open Valve “ B “ Open Valve “ B “ to depressurise the sample connection line, then disconnect the cylinder.
