These are chemicals that could cause damage to the physical surroundings through fire and/or explosion. Health hazards arise from chemicals with significant evidence that either brief exposure or long-term exposure can cause health effects in those that have been exposed.

When discussing the health effects of chemicals, two terms, toxicity and hazard, are often used. Toxicity is the ability of a chemical substance to produce injury once it reaches a susceptible site in or on the body. Hazard is the probability that a substance will produce injury under the conditions/manner of use.

Hazard refers to the inherent properties of a substance that make it capable of causing harm to human health or the environment. Exposure describes both the amount of, and the frequency with which, a chemical substance reaches a person, group of people or the environment.

What are chemical hazards and toxic substances? Chemical hazards and toxic substances pose a wide range of health hazards (such as irritation, sensitization, and carcinogenicity) and physical hazards (such as flammability, corrosion, and explosibility).

'Hazard': an object or situation that has the potential to harm a person, the environment or cause damage to property. ... 'Incident': any unplanned event resulting in, or having a potential for injury, ill health, damage or other loss. 'Injury': any physical or mental damage to the body caused by exposure to a hazard.

Fundamentally, there is no difference. OK, biochemical reactions typically involve biological molecules but let's consider what those biological molecules are. ... So, chemical reactions and biochemical reactions take place with chemicals which renders the latter type of reactions, chemical reactions.

Toxicity is an example of a chemical property. Toxicity is how dangerous a chemical is to your health, a particular organ, another organism, or to the environment. ... The exposure causes a chemical reaction or set of reactions. The net result of the chemical changes is the toxicity.
