Safety and the environment are activities that are an integral part of the TPM approach.


The HSE pillar is the cornerstone of the production with regard to the impact it can have on the teams and the image of the company. Abraham Maslow1 even identifies that security is the first need just after basic needs that are eating, sleeping… the JIPM defined security as “ the maintenance of peace of Mind 2. Without the serenity of working in good conditions, employees cannot be creative and motivated to improve work performance.

The challenge is to reach the 0 accidents and create a ” green ” culture.

Beyond that, a series of studies show that integrating and implementing a strategy that takes into account the safety of the environment makes it possible to increase the overall performance of the company:

  • One study shows that out of 6 major sectors (energy…), companies being considered as a leader in security and the environment have outperformed by 25%3.
  • A study in the pharmaceutical sector has shown that companies with more than average on a rating related to the environment and security, have outperformed the others by about 17%4.
  • A study also showed that investors increased their returns on investment by 25 ä 38% if they integrated into their strategy the security and the Environment5.
  • In general, studies show that there is a correlation between financial performance and an environmental policy in 85% of cases6.

Actions to be taken

Already, through the various activities of the previous pillars, the TPM has improved safety and the environment. For example, treating downtime and unreliability of equipment has reduced the sources of hazards. The autonomous maintenance allowed to teach the operators how to maintain properly and intervene correctly on the equipments7

There are nevertheless many actions and especially to structure the approach and to integrate into these elements in the policy of the company.

Reach the 0 accidents

  1. Identify and remove potential accident hazards According to the principle of Heinrich, focus on dangerous behaviors.
  2. Analyze the causes of accidents and near-accident.
  3. Remove the causes by integrating the rules of ergonomics and hygiene.
  4. Develop a risk prevention plan and staff training

The principle of Heinrich


Herbert William HEINRICH is an American engineer who specializes in safety at work. He is the founder of the principle of the same name, principle indicating, based on a study of accidents in 19318 :

Out of 330 accidents, 300 are almost accidents, 30 are accidents with only material damage, 10 are accidents with minor injuries and 1 is a serious accident.

This principle teaches us the following thing:

If we wait for a serious accident, we can wait a long time before we realize that there is a real security problem and that it is too late. For in the meantime, 300 almost accidents have occurred where these people were able to get away by chance.

We must therefore focus on the study of the weak signals that are the almost accidents to anticipate a serious problem.

Creating Green Culture

Ischikawa proposes that the TPM approach follow a 4-step process for the implementation of a green culture under this pillar9 :

  1. Build an environmental management system that includes the objectives of ISO14001 and 14004.
  2. Implement actions through the TPM approach.
  3. Create a system to reduce the impact on the environment in the production and development of products.
  4. Improve the information and training of all employees
