Immerse yourself in the world of LOTO – Occupational health and safety


Dive into the world of LOTO

Procedures must keep pace with Industry 4.0 smart manufacturing.

When it comes to taking the important first step in setting up your energy control procedures (OSHA Lockout / Tagout Standard 1910.146), the sky is the limit. Lockout / Tagout (LOTO) is a key safety program when working with any power source including electricity, hydraulic pressure, air pressure, water pressure, energy thermal and even pyrophoric chemicals that burn on contact with air.

While companies dive deep into the world of LOTO, their approach is generally holistic. What separates the few greats from the rest of the overworked industry is how the program unfolds from that point on.

  • As facilities are upgraded, are LOTO procedures updated to reflect these changes?
  • Are specific isolation valves and electrical disconnectors in place for each new production line?
  • Are annual evaluations carried out? The answer to this last question is frequently: no. Few companies follow up on their annual reviews, and only a fraction bring a qualified fresh perspective to ensure that the process is carried out optimally. Why? Because the annual review process tends to become one more task for overworked security professionals.

Business growth can also become the source of many challenges, especially if security programs are not properly sized. Growth beyond safety programs is one of the main reasons the 1910,147 Hazardous Energy Control (Lockout / Tagout) is on OSHA’s 10 Most Cited Standards list year after year.
