Is 4 inhalation the only way a hazardous material can enter your body
The different ways a person can come into contact with hazardous chemicals are called exposure pathways. There are three basic exposure pathways: inhalation, ingestion, and skin contact. Inhalation is breathing or inhaling into the lungs. Ingestion is taking something in by mouth.

What is class 4 hazard class
Flammable Solids
Hazard Class 4 – Flammable Solids
These are the three divisions of flammable solids along with a common example for each: Flammable solid (4.1) (e.g., match sticks), Spontaneously combustible material (4.2) (e.g., oily rags) Dangerous when wet (4.3) (e.g., magnesium fire starter)
What is hazard class 4
Class 4 Flammable Solid. Class 4 materials undergo combustion without outside changes to density or pressure. They are also prone to combustion without the assistance of chemical accelerants. The U.S. Department of Transportation breaks this hazard class into three general categories: 4.1 Flammable Solids.
What is a Level 4 hazard
Levels 4: These substances are corrosive or reactive and require extensive safety procedures to be appropriately handled. They could cause death within a matter of minutes or hours, such as hydrogen cyanide.
