What is fire and explosion hazards?
Fire and explosive hazards include combustible and flammable liquids and substances, and/or when hot work is performed. Fire and explosion can occur when the temperature has reached the flash point of the volatile material, and where there is sufficient vapour present in the atmosphere.
What are explosive hazards?
In mining, explosives are the most obvious form of explosion hazard. Explosions can be: chemical – high explosives, gas ignition, and fine particulate or dust sulphide dust ignition (SDI) electrical or magnetic – high current arc flashes or excessive magnetic pressure in an ultra-strong electromagnet.
What is fire and explosion hazards assessment?
Fire and explosion hazard assessment is the process of conducting hazard assessments and ensuring all ignition, oxygen, and fuel sources are identified at or adjacent to the proposed work site or industrial process.
What are the types of fire hazards?
Common Fire Hazards
- Arson.
- Cooking.
- Smoking materials.
- Open flame (i.e., candles/incense)
- Electrical (wiring, appliances and equipment) hazards.
- Residential furnishings.
- Accumulation of combustible materials.
- Improper handling and storage of combustible/flammable liquids.
What is the cause of fire and explosion?
For a fire to start or an explosion to occur, fuel (a flammable substance), air and a source of ignition are all needed.
What are the causes of fire hazard?
Top fire causes Cooking, heating, electrical, smoking, and candles….
- Candles.
- Cooking.
- ElectricalExpand sub-navigation. Electrical circuit-interrupters. Tamper-resistant electrical receptacles. LED lighting.
- Heating.
- Smoking.
What is a flammable hazard?
Flammable liquids are among the most common hazardous chemicals found in a laboratory. The primary hazard associated with flammable liquids is their ability to readily ignite and burn. The National Fire Protection Association (NFPA) defines a flammable liquid as a liquid whose flash point does not exceed 100°F (38°C).
What causes fire explosion?
Is explosion a hazard or risk?
The effects of accidental fires or explosions can be devastating in terms of lives lost, injuries, damage to property and the environment, and to business continuity. Working with flammable liquids, dusts, gases and solids is hazardous because of the risk of fire and explosion.
What are the dangers of fire hazard?
Firstly the fire will deplete oxygen from the surrounding atmosphere. Most casualties from a fire die from the smoke and lack of oxygen. Secondly, especially where plastics are being burnt, the fumes could be toxic, and anyone exposed could die. The heating effect from a fire also causes other hazards.
Which is more dangerous a fire or an explosion?
Spontaneous combustion and non explosion proof electrical equipment is the potential ignition source. Fire occur in industry is more frequently than explosions and toxic release, although the consequences in terms of loss of life are generally less. Therefore fire might be less hazardous.
How are flash points related to fire hazard?
Flash point is directly related to a liquid’s ability to generate vapor. Since it is the vapor of a liquid, not the liquid itself, that burns, vapor generation becomes a primary factor in determining the fire hazard. Flammable liquids have flash points below 100oF and are classified as Class I liquids.
What are the regulations for control of fire and explosion?
CONTROL OF FIRE AND EXPLOSION Fire protection provisions are applicable to bulk drug industries, whether synthetic,biological or microbiological. Government regulations are available for safety in fire protection.
Which is an example of a high hazard item?
High hazard contents are those which are liable to burn with extreme rapidity or which may produce poisonous fumes or explosions in a fire. Examples include flammable chemicals and grain. Author Stephen Lane Created Date
