Probe is proudly an authorised distributor in South Africa and Africa for Master Lock products. Master Lock is recognised around the world as the authentic, enduring name in safety products and padlocks. 



Numerous industries from mining, to power utilities and manufacturing, need to operate potentially hazardous equipment in order to get the job done.  These industries are required by a globally-accepted safety standard (the 29CFR 1910.17), to use lockout-tagout (LO/TO) or lock and tag methods as a safety procedure.   Probe, through the provision of Master Lock’s  line of safety lockout/tagout products is ideally positioned to assist companies in meeting the standard’s requirements.

The safety standard, which was introduced by the United States Occupational Safety and Health Administration (OSHA) 30 years ago, requires that hazardous energy sources be “isolated and rendered inoperative” before work is started on the equipment in question. The isolated power sources are then locked and a tag is placed on the lock identifying the worker who placed it. The worker then holds the key for the lock, ensuring that only he or she can remove the lock and re-start the machine once work is completed. This prevents accidental start-up of a machine while it is in a hazardous state or while a worker is in direct contact with it. These safety specific work procedures safeguard employees from accidental injuries or even death.


Probe offers the comprehensive Master Lock exclusive product line of accessories which includes innovative and patent-pending cable lockouts, gate valve, ball valve, circuit breaker, plug covers and much more. Available individually or in modular kits and stations, these products are effective and easy-to-use.



The Master Lock Safety Series products and services are designed to help you successfully develop and implement the best possible lockout/tagout system for each facility. 



Environmentally preferable products


Additionally, a number of Master lock products have been UL Environment Verified for recycled contents. UL Environment works to advance global sustainability by supporting the growth and development of environmentally preferable products, services and organisations. Master Lock safety padlocks use FDA compliant lubricants, which are safe for use in food processing facilities.


With Probe and Master Lock, industrial environments are able to remain compliant and, most importantly, safe.   Because while it may be important to satisfy regulations, preventing accidents and protecting employees is the number one priority.
