Qualitative safety advice, training &

occupational hygiene measurements.


A selection of the most interesting projects to date..
Industrial Hygiene
- Measurements
- Risk:  modelling  
  qualitative or quantitative  

The most fascinating hygiene measurement campaign took place in Norway.  At a pilot installation for refining metals at high temperatures, the dust exposure was mapped by more than 50 stationary and personal measurements (950-element analysis). This was evaluated in accordance with EN-689 and the Norwegian legislation.

Risk-Analysis and
Safety and Health Standards

Different kind of risk analyses can be performed in the domain of safety and occupational hygiene. The risks are identified company-wide. This is supplemented by department specific analyses like mobile work equipment and traffic safety, noise analyses, HAZOP's, SWIFTS, ...

Over the years there safety standards have been developed.

Official validation of the Risk Analysis and the action plan in the Netherlands is possible.

Proactive KPI's
for being ahead of Incidents...

Sometimes it is possible to predict and prevent incidents with well defined pro-active safety-KPI's and goals. 

The possibility to define these KPI's depends on the safety maturity of the company which is company-specific. 

Tracking the
Critical Risks

Every entrepreneur wants to prevent fatal or serious accidents with permanent disabilities. HYSA has a methodology to make these Critical Risks visible and resolve them.


It is important that all data is collected immediately after an incident. HYSA uses the ICAM-methodology (Incident Cause Analysis) for the investigation and analysis. ICAM finds its origin in the aerospace industry of Australia. It is a structured way to find underlying causes and makes the root causes visible. A fault tree or a cause tree is then easily put together.
