Qualitative safety advice, training & occupational hygiene measurements.


A selection of the most fascinating projects to date... 
Industrial Hygiene:
- Measurements
- Risk-Analysis: qualitative and quantitavive  

The most fascinating occupational hygiene measurement campaign was in Norway. At a pilot installation to refining metals at high temperatures, dust exposure has been mapped with more than 50 stationary and personal dust measurements (950 element analyses). This was evaluated in accordance with EN-689 and Norwegian legislation.

Detecting Critical Risks

Every entrepreneur wants to prevent fatal or serious accidents with permanent disabilities. HYSA has tested a methodology where it can make these critical risks visible and offer solutions.

Risk Analysis and Safety and Health Standards

Different kind of risk analysis can be performer in the domain of safety and occupational hygiene. The risks are identified company-wide. This is supplemented by department specific analysis such as mobile work equipment and traffic safety, noise analyses, HAZOPs, SWIFTS, ...

Safety & Health standards or procedures could be developed out of the risk analysis.

Proactive KPIs to get ahead of incidents...

It is important that all data immediately is collected after an incident.

HYSA uses the ICAM methodology (Incident Cause Analysis Method) 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 fact tree or cause tree is then easy put together.


Sometimes it is possible to anticipate or predict accidents with well-defined proactive safety KPIs and goals.  They are leading indicators that are statistically much more accurate than subsequent indicators. The possibility of setting them up depends on the safety requirementsmaturity of the company and is therefore company specific.
