CHEMICAL HAZARD & SAFETY
THE BASIC CHEMICAL HAZARD CLASSIFICATION
![Page 2: CHEMICAL HAZARD & SAFETY THE BASIC CHEMICAL HAZARD CLASSIFICATION.](https://reader033.fdocuments.in/reader033/viewer/2022061402/56649e895503460f94b8da29/html5/thumbnails/2.jpg)
CLASSIFY CHEMICAL HAZARD
The hazard of a chemical needs to be classified for the safe handling, storage, transportation and disposal of toxic chemicals & hazardous wastes
![Page 3: CHEMICAL HAZARD & SAFETY THE BASIC CHEMICAL HAZARD CLASSIFICATION.](https://reader033.fdocuments.in/reader033/viewer/2022061402/56649e895503460f94b8da29/html5/thumbnails/3.jpg)
WHY CLASSIFY THE HAZARD?
Rapid determination of the hazardous substance present and the evaluation of the potential threat to people and the environment;
Determine actions that are needed to isolate the hazardous substance and prevent injury or death;
To prepare for safe transportation to storage area or disposal facility; and
Identify the best place for disposal of the toxic and hazardous waste.

BASIC CHEMICAL HAZARD CLASSIFICATION Use of qualitative analysis to
classify hazard into one of 9 Categories
The 9 Categories are those used internationally on Placards
Identify the toxicity or toxicological properties of the toxic hazardous wastes
![Page 5: CHEMICAL HAZARD & SAFETY THE BASIC CHEMICAL HAZARD CLASSIFICATION.](https://reader033.fdocuments.in/reader033/viewer/2022061402/56649e895503460f94b8da29/html5/thumbnails/5.jpg)
9 HAZARD CATEGORIES
Class 1 - Explosives Class 2 – Flammable Gases Class 3 – Flammable/Combustible Liquids Class 4 – Flam. Solids/Dangerous When
Wet Class 5 – Oxidizers and Organic Peroxides Class 6 – Toxic Materials/Infectious
Substance Class 7 – Radioactive Materials Class 8 – Corrosive Materials Class 9 - Miscellaneous

CHEMICAL & PHYSICAL TERMS
Common Chemical Terms:Product: Unused chemicals with known
characteristics. Provided in Material Safety Data Sheets
(MSDS)Non-Product: Used chemical (spent), or Wasted into unknown situations, or When mixed with other unknown wastes,
no longer has known characteristics. It is now a hazardous waste
![Page 7: CHEMICAL HAZARD & SAFETY THE BASIC CHEMICAL HAZARD CLASSIFICATION.](https://reader033.fdocuments.in/reader033/viewer/2022061402/56649e895503460f94b8da29/html5/thumbnails/7.jpg)
CHEMICAL & PHYSICAL TERMS(continued)
Hazardous Substances: Any hazardous chemical elements or compounds or hazardous wastes or a combination of the above.

SUMMARY
• Classify the toxic hazardous wastes for:
– Protection of human health• Workers, people, food
– Protection of the environment• Water, vegetation, air, soil
– Safe handling, storage, transportation and disposal of toxic hazardous wastes
![Page 11: CHEMICAL HAZARD & SAFETY THE BASIC CHEMICAL HAZARD CLASSIFICATION.](https://reader033.fdocuments.in/reader033/viewer/2022061402/56649e895503460f94b8da29/html5/thumbnails/11.jpg)
SEGREGATION AND SEPARATION OF TOXIC & HAZARDOUS MATERIALS
![Page 12: CHEMICAL HAZARD & SAFETY THE BASIC CHEMICAL HAZARD CLASSIFICATION.](https://reader033.fdocuments.in/reader033/viewer/2022061402/56649e895503460f94b8da29/html5/thumbnails/12.jpg)
WHY SEGREGATE AND SEPARATE?
• Safety– Transportation (trucks, rail boxes)– Shipping– Storage (warehouse, storerooms, temporary
indoors or outdoor areas)• Reduce hazardous & toxic materials’ harm
– To citizens– To environment– To workers
• International system apply (GHS)
![Page 13: CHEMICAL HAZARD & SAFETY THE BASIC CHEMICAL HAZARD CLASSIFICATION.](https://reader033.fdocuments.in/reader033/viewer/2022061402/56649e895503460f94b8da29/html5/thumbnails/13.jpg)
Segregation & Separation Using International Labels
• Separated & segregated based on IWIC, ICAO or similar systems
• Labels: found on “small things” - packages– Labels look like Placards, except
• Labels are smaller (1/3 the size of Placards)• Labels are on boxes, cylinders, drums and
bottles– Labels indicate the hazard the same as those in
the Placards• Placards are on trucks, rail cars – “big things”
![Page 14: CHEMICAL HAZARD & SAFETY THE BASIC CHEMICAL HAZARD CLASSIFICATION.](https://reader033.fdocuments.in/reader033/viewer/2022061402/56649e895503460f94b8da29/html5/thumbnails/14.jpg)

Segregation of Hazards
• Concept: Do not place one hazard in the same place as another hazard
• Example: flammable with toxic gas
![Page 17: CHEMICAL HAZARD & SAFETY THE BASIC CHEMICAL HAZARD CLASSIFICATION.](https://reader033.fdocuments.in/reader033/viewer/2022061402/56649e895503460f94b8da29/html5/thumbnails/17.jpg)

Low Hazard Storage Area
Unlabeled low hazard materials (e.g., combustible lubricant or oil) and certain labeled low hazard materials (e.g., lime, label ORM-B) may be stored in a general purpose facility or area
![Page 33: CHEMICAL HAZARD & SAFETY THE BASIC CHEMICAL HAZARD CLASSIFICATION.](https://reader033.fdocuments.in/reader033/viewer/2022061402/56649e895503460f94b8da29/html5/thumbnails/33.jpg)
Additional Storage Recommendation Material with more than one hazard (e.g., flammable and
poison) should be stored in an area designed to store both types of hazard.
Compressed gas cylinders are preferably stored out of doors, protected from the ground beneath and direct sunlight.
Separation/ segregation should e by physical means (walls) where possible.
Other regulated materials (ORM) should be stored in an area designated for primary hazard of the material (e.g., flammable aerosol, ORM-D, should stored as a flammable liquid).
Storage area must meet standard requirements for the hazard.
![Page 34: CHEMICAL HAZARD & SAFETY THE BASIC CHEMICAL HAZARD CLASSIFICATION.](https://reader033.fdocuments.in/reader033/viewer/2022061402/56649e895503460f94b8da29/html5/thumbnails/34.jpg)

The consequence of these reaction may result in personal injury, death, property damage, and adverse environmental impact.
Avoid mixing incompatible chemicals Separate/ segregate incompatible chemicals When in doubt, consult supervisor.

Flammable Liquid
Flammable material can: Burn rapidly Give off intense heat Produce heavy smoke Spread rapidly to other areas.
Some chemicals evaporates making the work area unsafe…flammable
Evaporation is increased by elevated temperatures.
![Page 38: CHEMICAL HAZARD & SAFETY THE BASIC CHEMICAL HAZARD CLASSIFICATION.](https://reader033.fdocuments.in/reader033/viewer/2022061402/56649e895503460f94b8da29/html5/thumbnails/38.jpg)
Corrosive Some chemicals will
breakdown into corrosive/ poisonous gases/fumes
Applies to hazardous materials labeled: TOXIC, POISON, RADIOACTIVE, ETIOLOGIC AGENTS and others.
Corrosive materials can burn your skin eyes.

Toxic/Poison
Principal Hazards Poisoning Fire Environmental
contamination
Fumes, vapors and dust pass quickly into the bloodstream from the lungs
![Page 40: CHEMICAL HAZARD & SAFETY THE BASIC CHEMICAL HAZARD CLASSIFICATION.](https://reader033.fdocuments.in/reader033/viewer/2022061402/56649e895503460f94b8da29/html5/thumbnails/40.jpg)
Explosive Some chemicals will
EXPLODE in the presence of heat or flame.
Hazardous materials such as Flammable Liquids and Compressed Gasses can react like explosive materials.
![Page 41: CHEMICAL HAZARD & SAFETY THE BASIC CHEMICAL HAZARD CLASSIFICATION.](https://reader033.fdocuments.in/reader033/viewer/2022061402/56649e895503460f94b8da29/html5/thumbnails/41.jpg)
Water Reactive Spontaneously Combustible
Flammable solid include water-reactive and spontaneously combustible materials.
Water-reactive materials are likely to become spontaneously flammable or to give off flammable or toxic gasses when in contact with water.
Spontaneously combustible materials are likely to burn
