When you work with highly flammable or otherwise hazardous materials, you have a duty to ensure that they are stored in safe conditions and in compliance with the law. Legislators demand that the strictest fire protection regulations be adhered to to protect people and the environment. Therefore, you should inform yourself at an early stage about the various requirements and define measures that best prevent fire risks.
In our practical guide we identify the fire safety aspects that should be considered in your risk assessment and which national and international regulations and standards play a role.
Fire protection refers to the measures put in place to (a) prevent the emergence and spread of a fire (b) to ensure the safety of people and animals and (c) the measures put in place to ensure effective fire extinguishing in the event of a fire.
When planning a hazardous goods warehouse, preventive fire protection must be taken into account, in order to minimize possible fire hazards due to the stored substances in advance or to prepare measures for effective fire fighting in the event of an emergency. It is divided into structural, technical and organizational measures:
|Structural Fire Protection
||Technical Fire Protection
||Organisational Fire Protection
In order to define and implement suitable fire protection measures, you should first of all know the dangers that can be expected in your company. Is there any risk of fire due to dangerous substances in the company? If such a fire hazard exists, how high is this? All this should be determined in your risk assessment.
A risk assessment should be carried out for all operations in which activities with flammable or oxidizing hazardous substances are used. Especially with regard to identifying fire hazards and the measures needed to eliminate risks from hazardous materials.
Before work is carried out, employers must assess the fire risks that may be caused by dangerous substances. This should be carried out as part of a risk assessment and by a competent, trained professional.
All relevant factors for the rise, spread and impact of a fire must be considered. These include the dangers for employees from smoke, other (toxic) fire products, heat and the failure of components. For a good overview, here are some handy questions to ask yourself:
|To the hazardous substances present during operation|
|Are activities carried out with combustible or oxidizing hazardous substances or can flammable or oxidizing hazardous substances be generated or released during activities?|
|Is there a possibility of a substitution of hazardous substances or a process change in operations which would help minimize the risk?|
|At which locations, in which quantities and in which state are flammable or oxidizing hazardous substances present?|
|Which dangerous properties do the hazardous substances have, which fire hazard results from this, and which follow-on products are to be expected?
Our tip: Consult the safety data sheets. These contain important safety-related information from the supplier regarding the respective substances. In the assessment, it should be taken into account that deviating test parameters may be the basis, depending on the test method.
Which physicochemical properties and safety parameters do the flammable substances have?
|To the operational and local conditions|
|What is the influence of working equipment or systems and their operation?|
|How do structural, local and operational conditions as well as working conditions, organization and environment affect the fire risk?|
|Are there possible interactions?|
|How is the fire hazard to be assessed taking into account various operating conditions?
These include: normal operation, commissioning and decommissioning of equipment or work equipment, breakdowns, foreseeable improper operation.
|Are there operating conditions that require separate measures?
These include: maintenance (maintenance, inspection, repair, improvement) and the commissioning and decommissioning of safety equipment.
|Which persons are to be expected locally and in which number?|
|Are special working conditions (for example long or confusing escape routes or scaffolding work) to be taken into account?|
|How fast can the fire department be on site and what equipment does it have?|
|How should the physical boundary conditions be assessed?
E.g. Temperature, air flows, humidity, room volume, room area, room height
|Possible sources of ignition|
|Are works carried out with an open flame or high temperatures?|
|Can ignition sources be generated by improper operating conditions?|
|Are there any effects from electrical, mechanical, chemical and / or thermal energy?|
|How effective are the ignition sources?|
|On licensing and other requirements|
|Which building regulations requirements are required with regard to preventive and defensive fire protection?|
|Are requirements already known from previous reports?
E.g. from fire safety reports, fire protection concepts according to the building permit, risk assessments, safety reports according to accident regulations, etc.
Employers must put control measures in place to eliminate risks from dangerous substances, or reduce them as far as is reasonably practicable.
The best solution is to eliminate the risk completely by replacing the dangerous substance with another substance, or using a different work process, but in practice this may be difficult to achieve. Where it is not possible to eliminate the risk completely employers must take measures to control risks and reduce the severity of the effects of any harmful event.
When the risk cannot be eliminated, control measures should be applied in the following priority order:
In addition to control measures, employers should put mitigation measures in place. These measures should be consistent with the risk assessment and appropriate to the nature of the operation and include:
Arrangements must be made to deal with emergencies. These plans and procedures should cover safety drills and suitable communication and warning systems and should be in proportion to the risks. If an emergency occurs, workers tasked with carrying out repairs or other necessary work must be provided with the appropriate equipment to allow them to carry out this work safely.
The information in the emergency plans and procedures must be made available to the emergency services to allow them to develop their own plans if necessary.
Employees must also be provided with the relevant information, instructions, and training. This includes:
For example, when planning a hazardous goods warehouse, observe the following aspects (note: the above-mentioned measures in case of increased or high risk of fire are partly mutually reinforcing.) Measures with high risk of fire can replace the measures with increased risk of fire):
|Increased fire hazard
- in addition to basic duties -
|High fire hazard
- in addition to basic duties -
|Structural Fire Protection||Spatial separation through safety or safety distances
Fire safety adequately dimensioned structural separation
Possibly. Increased stability through adequate fire resistance
Use of a tight enclosure with increased resistance (e.g., hazardous goods packaging)
Distribution of fire-hazardous substances into fire-resistant, separated areas
Fire protection dimensioning of the enclosures as part of the sytem
|Plant Fire Protection||
Avoidance of ignition sources
|Avoid the entry of ignition sources into the interior of systems by technical measures
Inerting, oxygen reduction
Area-wide or property-related fire alarm system (BMA) with fire control and alarming of employees or the fire department
Alerting (through technical equipment such as visual-acoustic alerting, etc.)
Increased stability through cooling, sprinkling systems
|Organizational Fire Protection||Avoidance of ignition sources
Use of personal protective equipment to avoid ignition sources
Compliance with special requirements
Ban on fire and naked lights, no smoking
Use of work permit procedures (when working with an open flame, working with pure oxygen)
Prohibition of working alone
Ensure adequate oversight
Control for early fire detection through tours or the presence of staff
Organizational fire protection and extinguishing measures
Training an increased number of workers to fight fires
Shortening of escape routes, additional emergency exits, additional escape routes
Establishing collection points
Coordinated fire-fighting measures
Assigning people to organize the escape from the building
Creation of protection areas
In the context of the risk assessment, the effectiveness of the protective measures must also be checked. Since this is difficult in practice before the occurrence of an actual fire, a theoretical assessment must be used. The selected protective measures are to be examined to see whether they can be expected individually or in combination the desired success - but also to investigate possible negative interactions. As soon as there are procedural changes or other relevant changes, the risk assessment must be updated and, if necessary, the fire protection measures adjusted. Technical protective measures must also be subjected to regular functional tests. According to TRGS 800, these must be carried out every three years or at shorter intervals if this has been determined as the result of the risk assessment. The results of the risk assessment and the regular functional tests must be documented in a suitable form.
Especially when it comes to fire protection in connection with the storage of hazardous substances, special potential hazards arising from the stored substances have to be taken into account. In addition to the individual risk assessment, companies can also obtain specific information on fire protection measures from various regulations dealing with the safe storage and handling of hazardous substances.
Anyone who stores hazardous substances has to consider the possible fire hazards and the numerous regulations that surround it. Building regulations must be met and specific requirements for the storage of hazardous materials also play a role.
