• I relocate electrical distribution boxes at my construction site or add an extra box.
• I often replace the plug of a sawing machine and reel myself.
• I do not fully unwind my reel when this is not necessary.

Electrical power is the energy source for light, motion, heat and signals.

• Electrocution
• Burns
• Fire hazard
• Explosion hazard

• Most of the hazards are created by:

• Installing, adjusting or expanding the installation by users;
• No or insufficient knowledge on the part of users;
• Making use of faulty, non-inspected or the wrong materials;
• The improper installation of electrical installations.

• The characteristics of the power supply are determined by many factors, such as:

• Current intensity;
• Type of current (direct/alternating current);
• Environmental conditions (climate) in which the work is performed (water, moisture, temperature, etc);
• Cables lying on walking and driving pathways, without protection, in water, etc;
• Other construction site factors and facilities;
• Cable rolled up on reels, which operate as coils and ultimately burn right through.

• Things you are NOT permitted to do as an employee or foreman:

• Relocate the main distribution box yourself; this is the responsibility of HMB;
• Remove the earthing pin from the ground and/or replace it;
• Endlessly daisy chain electrical distribution boxes;
• Replace parts;
• Taper cables;
• Lay cables on walking or driving pathways; this will cause them to become damaged;
• Place distribution boxes or cables in water.

• Engage the HMB person responsible for the installation when the electrical installation is to be adjusted or relocated;
• In case of malfunctions or a failure of the electrical installation, always contact the HMB service department and if possible, visually check to see if you can determine the possible cause;
• Add a single distribution box through means of daisy chaining;
• Always fully unroll reels and/or cables;
• The foreman has a copy of the drawing of the construction site’s electrical system provided to him/her by the HMB person responsible for the installation;
• Keep the electrical installation clean, do not carry out any machining or wet, spattering activities immediately adjacent to a distribution box and do not use it as a workbench;
• Only make use of inspected electrical tools;
• Visually check electrical tools and the electrical installation for possible visible defects prior to use.

Tips for working safely

• Electricity always is a potential danger, even without direct contact. 
• Do not perform any work on an installation or electrical equipment, but contact HMB Construction Site Systems!
• Only a trained person is permitted to work on an electrical installation.
• Do not relocate any installation components that are not meant to be relocated.
• Adhere to the above-referenced rules and regulations!
