10.1 Purpose and Safe Operation of Vehicle Technical Equipment
Key Takeaways
Know fitted equipment’s purpose, controls, capacity, checks and safe stop procedure before operating it.
ADR basic training does not replace vehicle-specific instruction or tank specialisation.
Engine use for loading appliances requires both operational necessity and permission under the country’s law.
Never bypass an interlock, loosen a pressurised connection or use damaged lifting equipment to meet a schedule.
Technical equipment is a compulsory basic-course subject
ADR 8.2.2.3.2(h) covers the purpose and method of operation of technical equipment on vehicles. This includes more than carrying extinguishers and gloves. The driver must understand what fitted equipment does, the limits of their training and how to stop an operation safely. A basic course does not replace employer instruction on a particular vehicle, tail-lift, pump, compressor or loading installation.
Start with the vehicle’s authorised procedure and controls. Locate the normal stop, emergency stop, isolation controls and warning indicators before use. Check that guards and interlocks work and that the equipment is suitable for the intended operation. Never bypass a defect because the load is urgent. A control labelled “off” may stop motion without isolating stored hydraulic, pneumatic or electrical energy; maintenance requires the authorised isolation process.
Match the equipment to its purpose
| Equipment | Purpose | Core-driver precaution |
|---|---|---|
| Parking brake and applicable chocks | Prevent unintended movement | Secure before handling; check 8.3.7 and site rules |
| Tail-lift/loading crane | Move packages between levels | Use only with training, rated capacity and safe positioning |
| Container twist-locks/attachment devices | Retain the container on the carrying vehicle | Verify engagement through the approved inspection process |
| Pump or compressor | Transfer product in the authorised system | Product/pressure compatibility, correct connection and specialist training matter |
| Earthing connection | Reduce hazardous static potential where required | Establish the required good electrical connection before the applicable transfer |
| Temperature-control/monitoring system | Maintain assigned carriage conditions and warn of deterioration | Know the control/emergency temperature response and do not silence a fault as a remedy |
| Battery master switch, if fitted | Disconnect specified vehicle circuits | Know its location and use as instructed; it is not an all-purpose chemical emergency cure |
Pre-operation inspection and work area
Inspect for visible damage, fluid leaks, loose parts, missing guards and failed indicators. Confirm the work area is firm and appropriately level, with enough space and exclusion from moving traffic. The vehicle must be suitably parked and secured. Consider overhead obstacles, pedestrians, pinch points and whether a loading platform can trap a package or crush its closure.
For a tail-lift, the rated load includes the relevant load and handling equipment within the permitted load-centre arrangement. A heavy pallet at the outer edge may exceed the permitted moment even when its mass seems below the headline rating. Consult the rating plate and instructions rather than making up a universal mass limit. Keep people out of the travel path and do not ride equipment unless its design and procedure permit it.
Do not place forks, hooks or straps against a dangerous goods package in a way that can puncture or distort it. An IBC frame is not automatically a lifting point for any crane arrangement. Use the package/container’s intended handling features and approved attachments. A visibly damaged lifting point calls for assessment, not a stronger tug.
Engines, pumps and compressors
ADR 8.3.6 normally requires the engine to be shut off during loading/unloading. The exception is where it is needed to drive pumps or other loading/unloading appliances and the country’s law permits that use. This does not give permission to idle for comfort or ignore site ignition rules.
Pumps and compressors create pressure and can move hazardous material unexpectedly. Only trained authorised operators should connect and operate the actual transfer system. Confirm the destination, product, compatible connections and receiving arrangements through the site procedure. Never use a hose’s colour as the sole product identification or change a coupling to overcome a safety interlock. Detailed tank filling/discharge instruction belongs in tank specialisation and vehicle/site training.
If flow, pressure, noise or temperature becomes abnormal, stop through the authorised procedure and report it. Do not loosen a pressurised connection to “see whether it is blocked”. Emergency isolation may stop supply while pressure or product remains trapped in a hose. Safe disconnection and maintenance require the trained procedure.
Earthing and ignition control
ADR 7.5.10 requires a good electrical connection to earth before filling or emptying tanks with flammable gases or liquids of flash point not exceeding 60°C, with precautions against electrostatic discharge. This is different from connecting protective earth on arbitrary electrical equipment. Use the designated system and prove its condition as the installation requires.
Portable lighting under 8.3.4 must have no metal surface liable to produce sparks. Additional goods-specific requirements such as S2(1) can apply to lighting/electrical equipment. A non-metal case alone does not establish that a phone or lamp is suitable inside a flammable atmosphere. Carrying suitable equipment is not permission to enter a contaminated compartment.
Temperature monitoring and breakdowns
For temperature-controlled goods, know the assigned control and emergency temperatures before departure. Check the actual display, recording and alarm arrangements and the authorised response to cooling failure. Monitor as instructed during the journey. A spare cooling system is useful only if it is approved, functional and correctly operated.
A refrigeration fault, damaged tail-lift or failed container lock must be reported promptly. Secure the vehicle/load and arrange qualified assistance. Do not repair electrical wiring near a possible vapour release or improvise transfer into another vehicle without establishing lawful packaging, documents and handling conditions.
Worked decision: damaged tail-lift
A driver collecting corrosive drums sees hydraulic fluid leaking from the tail-lift and the platform lowering unevenly. The correct response is to stop its use, keep people and packages clear, and obtain a safe approved alternative through the carrier/site. Putting an extra person on one side to balance the platform increases risk; it does not restore the lift’s rated performance. The dangerous goods label makes package damage especially serious, while the equipment’s safe-use principles remain essential for every load.

A tail-lift leaks and lowers unevenly. What should happen?
Stop its use and arrange a safe approved alternative
Add a person to balance the platform
Increase the load to stabilise it
Operate faster to finish before it fails
A sealed freight container has a damaged attachment lock on the carrying vehicle. What should the driver do?
Assume the container’s own weight prevents movement
Stop departure and have the attachment defect assessed and corrected through the approved procedure
Use the door seal as a substitute restraint
Ignore it if the goods are PG III
What does operating an emergency stop prove?
All stored energy and trapped product are gone
The equipment is safe to repair without checks
Only what the particular system is designed to stop; safe isolation still needs the authorised procedure
That pressure hoses can be opened immediately
