| Hazardous-area classification | Flammable gas, vapour, or combustible dust may be present during normal operation or under abnormal conditions. | Select equipment certified and marked for the specific hazardous area and substance. Gas zones are commonly designated Zone 0, 1, or 2; dust zones are designated Zone 20, 21, or 22. | Confirm the site zone, gas or dust group, required temperature class or maximum surface temperature, and the forklift’s complete certification marking. Do not assume one truck suits every zone. |
| Electrical components | Switching, damaged wiring, or a component fault can produce an arc, spark, or hot surface. | Depending on the certified design, protection may use flameproof enclosures, increased safety, intrinsic safety for suitable circuits, or dust protection. | Check that the protection concept and component ratings match the equipment certificate and the site classification. IEC 60079 standards cover different types of protection. |
| Battery and charging | Electrical faults, exposed connections, or charging-related heat and gases can create ignition risks. | Use the specified battery, protected connections, and approved charging arrangements. Charging may need to take place outside the classified area, depending on the site rules and equipment approval. | Follow the manufacturer’s instructions and site procedures for battery removal, charging, inspection, and replacement. Confirm that any replacement battery is approved for the truck configuration. |
| Motors, brakes, and drive system | Electrical faults, friction, or excessive operating temperatures can provide an ignition source. | Use components and temperature controls included in the certified truck design; maintain brakes, motors, and drive components to the specified condition. | Review the certification scope and maintenance instructions. Do not modify, replace, or repair protected components with unapproved parts. |
| Static electricity | Charge can accumulate on the truck, tyres, operator, or load and discharge as a spark in some environments. | Where required by the risk assessment and equipment design, use appropriate static-dissipative components and bonding or grounding measures. | Check the site’s static-control requirements and verify that tyres and other specified components have the required properties. Conductive or dissipative measures must be suitable for the operating surface and area. |
| Hot surfaces and combustible dust | Dust deposits or hot equipment surfaces can ignite combustible dust or contribute to a dust explosion. | Dust-protected equipment limits dust ingress and controls surface temperatures in accordance with its certified design. | Confirm the dust group and permitted surface temperature. Keep the truck clean using approved methods; accumulated dust can affect both safety and cooling. |
| Mechanical impact and sparks | Impact between materials, forks, or truck parts may create sparks or heat, depending on the materials and conditions. | Use the truck and attachments specified for the task; manage operating speed, loads, and contact with surrounding equipment. | Assess the material being handled, attachment compatibility, and impact risks. A truck’s electrical certification alone does not eliminate every mechanical ignition source. |
| Certification and workplace controls | A truck used outside its approved conditions, or maintained incorrectly, may no longer provide the intended protection. | Match equipment selection to the workplace risk assessment and keep the truck within its certified configuration and operating limits. | Verify applicable approval documents and markings, operator training, inspection records, maintenance procedures, and site-specific controls. ATEX equipment requirements and workplace requirements are addressed separately under applicable EU directives. |
