Bond Before the Liquid Starts to Flow

Controls to confirm

• Verify bonding and earthing before transfer: for conductive containers, use the approved system to bond the dispensing and receiving equipment and connect it to the designated earth. Inspect leads and clamps, use the specified clean metal contact points, and confirm required continuity checks are current. Maintain the connections throughout the transfer; stop if a connection is lost.
• Use the assessed transfer method: select containers, hoses and pumps approved for the liquid and service. Follow the specified flow rate and filling arrangement to limit splashing and turbulence. An ordinary plastic container cannot be made safe simply by attaching a bonding clamp; refer non-conductive-container transfers for a competent assessment and an approved method.
• Control vapour and other ignition sources: use the designated ventilated dispensing area and the required hazardous-area equipment. Keep smoking, flames and unsuitable electrical equipment away, contain spills and close containers after use. Follow the safety data sheet and site procedure, including the specified protective clothing, gloves and eye protection.

Today’s action

Check one planned flammable-liquid transfer with the responsible operator. Trace the approved bonding and earthing connections, inspect their condition and confirm the transfer method; resolve any uncertainty before releasing the liquid.
