What is DSEAR? (Dangerous Substances and Explosive Atmospheres Regulations 2002)
DSEAR is concerned with the danger that can arise from fire, explosions and other events which involves dangerous substances in a workplace. Under this regulation, the minimum requirement for the protection of workers is set so that they could be kept safe from hazardous matter, gases under pressure, and corrosive substances. (How to Prevent Fires in the Workplace). For an explosive atmosphere, different ‘zones’ are allocated. These are categorized on the basis of the explosive atmosphere of the area.
It is necessary that after carrying out safety measures, an assessment should be performed. We provide services of risk assessment for explosive substances by our trained personnel having updated knowledge and experience.
Who Is Accountable for Compliance?
If you run a business or self-employed, you have the responsibility to take measures according to the regulations of D.S.E.A.R for the safety of the staff.
What Should an Employer Do?
Following are key points that should be considered by the employer in order to ensure safety.
What Needs to Consider for Dangerous Substances Assessment?
Aspects should be checked for assessment:
Explosives are hazardous and can create harmful effects physically such as heat radiation, oxygen depletion and others that may also lead to death.
To avoid any unwanted fire-related incidents and ensure safety, the Dangerous Substances and Explosive Atmospheres Regulations (DSEAR) needs to be implemented in the workplaces or work sites.
Any sites where explosives are produced, stored, used, or present come under the category of risk areas where risk assessments should be performed and safety measures should be taken properly.
What is DSEAR & When Do the Regulation Apply?
The types of activities that are covered under this regulation are:
DSEAR Is Applied to
Flammable gases, vapours, mists, or combustible dust can cause serious problems in the workplace like damage to the premises, financial loss, and life-threatening injuries to the workers. The explosive or flammable substances are required to be classified into different zones based on the risks they pose. It is crucial to reduce the risk of any undesired fire emergency.
Petrol is a highly dangerous substance which does not only cause a fire in liquid form but can also produce flammable vapours even at low temperatures. That means this commonly used fuel can be a serious risk in the presence of an ignition source.
Petroleum is covered under DSEAR specifically for its storage, dispensing, and use. Get Fire Extinguisher Training.
3. Substances Corrosive to Metal and Gases under Pressure
Pressurized gases (such as gases in the cylinder) give rise to the chance of explosion if not handled or stored correctly in the workplace. Additionally, the substances which corrode metals could be a source of structural damage, minimizing the integrity of the structures if not contained properly.
Cellulose nitrate is a material used in cinematographic films and photographic negatives by individuals or groups in homes or premises other than the workplace. These are also stored in homes and are very harmful as it catches fire easily which become difficult to put out.
Hazardous area classification can be defined as the method of analyzing and categorizing the environment where explosive gases or substances may occur. The major purpose of this classification is to assist the installation of the apparatus that can be used safely in that environment, considering the properties of explosive substances present in that premises.
Based on the frequency of occurrence and the time span of the explosive gas atmosphere, the hazardous areas are classified into different zones.
Many sources have tried to place time limits on to these zone classifications, however none have been officially adopted. Common values used are as follows:
