Extended Range of Master Safety Series Locks at Thornhill Security

Thornhill Security has now extended its lock range to include Master Safety Series Locks. Let us tell you why:

Each year thousands of accidents occur while repairing or servicing equipment. Most of these accidents are due to a failure to isolate power sources.  Therefore identification of the equipment’s potential hazard is essential for a successful safety prevention procedure.

The Risk

  • All energy sources are potential hazards for employees.  This can be mechanical, electrical, hydraulic pressure, gas, steam…
  • The EN 1038 norm relative to the equipment’s safety define the measures regarding the energy isolation of machinery and the power dissipation to prevent hazardous equipment re-energizing.  It assures a safe and secure intervention within a risk-prone area.
  • Essential warnings signs, tags out and devices must be shown on machinery to ensure employees’ safety.
  • Warnings signs must be chosen and shown so as it is clearly and easily seen and understood by all.
  • Equipment must have one or several lockout devices, chosen according to the energy sources to be locked out, clearly identifiable, accessible and in a sufficient amount to prevent hazardous situations.

 The Solution

  • Master Lock has developed Lockout systems, made from high resistant and patented material: temperature resistance, chemical and corrosion resistance, good UV stability…
  • Safety SeriesTM Lockout Systems are easy to use, intuitive, easily storable and assure safe and efficient isolation of the energy source.
  • Safety SeriesTM Lockout Systems are compliant with regulations: “1 employee – 1 padlock – 1 key”. The user has its own key. He is the only one to be able to open his own safety padlock.
  • Master Lock is concerned with employees’ safety and therefore uses its experience in the padlock profession to develop new lockout systems to better resolve technicians safety needs.

 All energy sources are potential hazards, these could be:

1. Electricity

2. Hydraulic Pressure

3. Compressed Air

4. Gas

5. Steam

6. And all Fluids

 Protect yourself and others against residual energy

Even when isolated, equipment can still retain some residual energy. So, some important procedures relating to Lockout/Tagout and Signs:

1. Identify the energy sources to be isolated

2. Be sure that:

a) The equipment that is being repaired/serviced can be isolated with a safety padlock or a lockout device.

b) The energy source can be isolated.  If this is the case, a safety padlock can be used.

3. Identify the person responsible for implementing identification labels and safety padlocks.

4. If several employees are working on the same equipment, make sure that each individual puts in place his own identification label and his own safety padlock.  Each energy source must be isolated and identified.

5. Make sure that no residual energy remains.  Note that even if energy is isolated, it is still very dangerous.

6. Ensure that company regulations regarding Lockout are followed at all times while operating on equipment.

7. Prior to removing safety padlocks and identification labels, make sure that

a) all forms of protection have been put in place,

b) maintenance is definitely completed and tools have been securely stored away,

c) employees are at their posts before reactivating machinery,

d) Control checks have been carried out and the machinery is ready for use.

8. Only the person in charge of locking out equipment with the relevant lockout device is permitted to remove it.  If several employees are working on the same equipment, the team supervisor must be the last to remove their lockout device(s).

9. Ensure that reactivation instructions are scrupulously followed prior to resuming work on the equipment.

10. Security is the responsibility of all.  Ensure that all personnel thoroughly understand the Lockout regulations.
