Chemical Interactions
This Subpart (letter) governs hazardous materials.
Subpart H
The acronym GHS stands for this.
Globally Harmonized System
Class 1 shows a picture of this item and its classification.
An explosion, explosives.
OSHA often refers to this organization for guidance on compressed gases.
The Compressed Gas Association.
The minimum temperature at which a liquid gives off a vapor within a vessel that allows an ignitable mixture to be formed.
Flash Point
Specifically, you never want to mix these two classifications of chemicals.
Oxidizer and flammable
The GHS was developed by this organization.
United Nations
Class 5 shows a picture of this item and its classification.
A circle with flames coming off of it, oxidizing agent.
High pressure is considered above this PSI.
900
The lowest point at which an ignitable mixture in the air can cause an explosion.
Lower Explosive Limit
When two chemicals serve to reduce each others effects.
Subtraction
GHS's purpose is this.
To standardize chemical manufacture warnings and information (SDS) so workers can better protect themselves.
Class 6 shows a picture of this item and its classification. (Hint: two items)

self.
When two chemicals serve to multiply each others reaction.
Potentiating effect
In addition to SDSs, this item was also standardized under the GHS.
Warning labels.
Class 8 shows a picture of this item and its classification.
Acid being poured into a surface and hands, corrosive.
If cylinders show signs of corrosion they are to be:
removed from service.
Flammable liquids are divided into this many categories.
Four.
This type of combustion is what happens when components spontaneously ignite when coming into contact with one another.
Hypergolic
Before the GHS introduced SDSs, this item was used in its place.
Material Safety Data Sheet.
Class 3 shows a picture of this item and its classification.
An open flame with a line under it, flammable liquids.
If flammable gas cylinders are stored indoors, they must be this many feet from other flammables or combustible materials.
20 Feet.
A flammable liquids flash point is this temperature.
199.4 Fahrenheit
