When chemical reactions are not properly managed, they can have harmful, or even catastrophic consequences, such as
toxic fumes, fires, and explosions
. These reactions may result in death and injury to people, damage to physical property, and severe effects on the environment.

What is a dangerously reactive material?
Dangerously Reactive Materials are
unstable or highly reactive materials that can undergo extremely hazardous uncontrolled reactions
. They can cause explosions, fires or extreme heating, with potential for significant personal injury and property damage.

- ammonium perchlorate.
- azo and diazo compounds.
- acetylides.
- azides.
- fulminates.
- hydrogen peroxide solutions (91% by weight)
- many organic peroxides.
- nitro and nitroso compounds.
How do you know if a chemical is dangerous?
To identify if a substance is hazardous,
check the product’s container label and/or the SDS which is available from the supplier
. … The labels of hazardous chemicals usually contain the words ‘danger’ or ‘warning’, along with relevant pictograms and details of hazards.
What is the most dangerous chemical in world?
1.
Botulinum toxin
. Scientists differ about the relative toxicities of substances, but they seem to agree that botulinum toxin, produced by anaerobic bacteria, is the most toxic substance known. Its LD50 is tiny – at most 1 nanogram per kilogram can kill a human.

What does it mean if a material is reactive?
Reactive materials are commonly regarded as
those materials that can be hazardous by themselves when caused to react by heat, pressure, shock
, friction, a catalyst, or by contact with air or water. Reactive interactions require the combining of two or more materials to pose a hazardous situation by chemical reaction.
How do you handle reactive substances?
Store dangerously reactive materials in suitable, labelled containers (usually their shipping containers) in a cool, dry area. Store, handle and use dangerously reactive materials in well-ventilated areas and away from incompatible materials.
What is the safety symbol for corrosive?
The exclamation mark pictogram
is used for the following classes and categories: Acute toxicity – Oral, Dermal, Inhalation (Category 4) Skin corrosion/irritation – Skin irritation (Category 2)
What are the three preferred methods of control at the source?
Elimination
(including substitution): remove the hazard from the workplace, or substitute (replace) hazardous materials or machines with less hazardous ones. Engineering Controls: includes designs or modifications to plants, equipment, ventilation systems, and processes that reduce the source of exposure.
What are examples of reactive substances?
Examples of highly reactive chemicals are
explosives, peroxides, water-reactives, and pyrophorics
. All work involving highly reactive chemicals should be approved by the laboratory supervisor before initiation of the work.
Which is an example of a reactive chemical?
Reactive chemicals are classified as explosives, strong oxidizing agents, water reactives, air reactives, and special organic compounds. … Many of these compounds become more sensitive as they age or dry out. Examples include
peroxides, nitroglycerin, and TNT
.
How do you get toxic fumes out of your body?
- Steam therapy. Steam therapy, or steam inhalation, involves inhaling water vapor to open the airways and help the lungs drain mucus. …

- Chest percussion.
What are the four major types of toxic substances?
Types. There are generally five types of toxic entities;
chemical, biological, physical, radiation and behavioural toxicity
: Disease-causing microorganisms and parasites are toxic in a broad sense but are generally called pathogens rather than toxicants.
What are the side effects of chemical exposure?
A small chemical exposure can cause
tearing eyes and burning of the eyes, nose, throat, chest and skin
