well i don't remember 3 but i have 2!
1.) some types of liquid like chemicals and things, why? because the vapor can hurt your eyes, lungs, and in long term may stop your heart. also because if you have anything like a backpack or food then chemicals could fall on those and you might either eat them and make you deathly sick or you might get them on your skin and get bad rashes or burns (same if chemicals just spill on you)
2.) some types of wood are hazardous because of the chemicals in them also. when the wood gets hot it could send off fumes that hurt you and other woods have chemicals that could get on your skin and burn you or I've u a rash. also if one gives you a splinter those chemicals or even just the wood could severely hurt that area.
hope it helped :)
A non hazardous material
The purpose of a control zone is to ensure that only properly trained, equipped, and protected people go where there is a potential for exposure to the hazardous material.
Hazardous material ceases to be hazardous when it is destroyed, sufficiently diluted in nonhazardous material, it is chemically changed into a nonhazardous material or incorporated into an object that immobilizes it and renders it unable to be hazardous.
It is the International Maritime Organization. This is a form used to describe hazardous materials in a container or shipping on a vessel. It is required for all hazardous material to be shipped via vessel.
A Hazardous Waste is any material that is subject to the EPA's Hazardous Waste Manifest specified in 40CFR262.

which hazardous material can enter the body
The term "hazardous" is used to refer to any material, condition, or situation that could cause injury, illness, environmental damage, death, or property damage. The term "non-hazardous" is used to describe a material, condition or situation that is thought not to be able to cause injury, illness, environmental damage, death, or property damage.
Its commonly referred to as hazardous waste or toxic waste.
a. a hazardous material is exposed to fire.
Hazardous wastes are materials that are to be discarded (i.e. are wastes) but can be a danger to people or to the environment and meet the definition based on the identity of the material or on test results. If hazardous wastes are mixed with the nonhazardous wastes, the result is a hazardous waste. A non-hazardous waste is something that is to be discarded (i.e is a waste) but does not meet the definition of a hazardous waste.
Polystyrene is not a hazardous material (dangerous good) in transportation. However, in circumstances where a fire might be a problem, polystyrene, which can readily and rapidly burn, can be a very hazardous material.
No - it is not usually considered hazardous
