What is BS EN 741 - Safety requirements for pneumatic handling of bulk materials about?
BS EN 741 is a European Standard on continuous handling equipment and systems. The main aim of BS EN 741 is to ensure the safer and more efficient transfer of bulk materials to maintain its quality and integrity.
BS EN 741 specifies the special safety requirements for those types of fixed pneumatic handling systems and components as defined in clause 3, which are designed for conveying bulk materials on a continuous or an intermittent basis (batch conveying system) from the loading point(s) to the unloading point(s).
BS EN 741 deals with the technical requirements to minimise the hazards listed in clause 4 which can arise during the operation and the maintenance of the pneumatic conveying system when carried out in accordance with the specifications given by the manufacturer or his authorised representative.
BS EN 741 applies to design, on site assembly and commissioning stages.
BS EN 741 applies also to the built-in actuators and parts of the systems, which control the components.
Note 1: BS EN 741 does not specify the requirements for any elements used as a link between a fixed part(s) of the system and any other part mounted on mobile/movable supports (e.g.: ship, unloaders, ...).
Note 2: BS EN 741 does not take into account the risks of burns and scalds by the radiation of heat sources or by contact with hot gases.
Note 3: BS EN 741 does not take into account the risk generated by ionising materials used in measuring equipment (e.g. level indicators).
Note 4: BS EN 741 does not specify the requirements for handling specific hazardous materials, such as radiating material, explosives, and explosive gases.
Note 5: BS EN 741 does not specify the requirements for hazards due to electrostatic charges of pipes and equipment made of non-metallic materials.
Note 6: The safety requirements for the transportation including loading and unloading of the components are not covered by BS EN 741.
Note 7: BS EN 741 does not apply to pneumatic conveying systems used underground, for mining and in public areas.
Note 8: BS EN 741 does not establish the additional requirements for: freezer applications, high temperatures, corrosive environments, strong magnetic fields, potentially explosive atmospheres, radioactive environment, operation on ships and earthquake effects, hazards during decommissioning.
Note 9: BS EN 741 does not specify the requirements for hazards due to noise.
Who is BS EN 741 - Safety requirements for pneumatic handling of bulk materials for?
BS EN 741 on the safety requirements for pneumatic handling of bulk materials is useful for:
- Manufacturers of pneumatically operated devices
- Materials handling equipment manufacturers and suppliers
- Installers of pneumatic conveying system
Why should you use BS EN 741 - Safety requirements for pneumatic handling of bulk materials?
The pneumatic conveying system is a system for the pneumatic conveying of loose bulk materials in pipes (ducts) by means of gas, usually air, including the piping and components and limited to them. Moving bulk goods via air through enclosed conveying pipelines is the primary principle of pneumatic conveying.
In this regard, BS EN 741 specifies the installation and maintenance of the system and its components, as well as their functional testing and training.
BS EN 741 clarifies the significance of risk assessment for this sort of equipment and system, as well as the actions that must be taken to eliminate or mitigate the risk.
BS EN 741 specifies the safety requirements and/or safety procedures for mechanical dangers, electrical hazards, thermal hazards, electromagnetic radiation hazards, biological and microbiological hazards, energy supply failure hazards, and other functional disorders.
BS EN 741 specifies procedures to protect against hazards that may arise during the inspection, maintenance, and cleaning, as well as safety signs and verification of safety standards and/or measures.
As a result, if you are a manufacturer of material handling equipment and systems, conforming to BS EN 741 can help demonstrate the performance and credibility of your product, ensuring that they are suitable for its purpose.
