Preventive Measures

If a workplace has a risk of contact with some biological hazard, the employer must determine, during the working environment risk assessment, the kind, extent and duration of the employee’s risk of infection. Based on the results, the employer must evaluate the hazard to the employees’ health and adapt adequate preventive measures. A risk assessment is mandatory when the work occurs in a:

  1. raw food handling and food manufacturing company;
  2. company manufacturing agricultural products and timber companies;
  3. contact with animals, livestock products and products manufactured from these;
  4. health care institution, including isolation facilities and morgue; nursing home;
  5. clinical, veterinary and diagnostics’ laboratory, except for diagnostic micro-biology laboratory;
  6. waste management location;
  7. sewage plant.

To decrease health hazards caused by biological hazards, the employer must:

  • Mark the work area influenced by the biological hazard and install warning signs “Biological Hazard” in required places.
  • Have as little employees in the hazard zone as possible.
  • Organize the work processes and handling of hazardous materials so, that the leakage of biological hazard factors into the working environment and their level of occurrence in the working environment would be as low as possible.
  • Collect contaminated waste and keep them in specially marked containers until their removal from the work environment.
  • Make contaminated waste as safe for health and the environment in autoclaves, by disinfecting, or by some other methodology.
  • Follow the food hygiene requirements.
  • Vaccinate employees who come in contact with biological hazard factors for which an effective vaccine exists. The employer must consult      the occupational health doctor regarding the need and appropriateness of vaccinating employees. Employees are vaccinated at the employer’s expense.
  • Specify the action plan for emergencies caused by biological hazards.
  • If necessary and technically possible, determine and monitor the content of biological hazard factors in the air of the working environment.

When it is not possible to transform the working environment safe by using the abovelisted means, the employees must be provided with personal protective gear and their proper use explained.

Following Occupational Hygiene Requirements

Occupational hygiene requirements must be followed in a working environment with biological hazard factors.

  • Forbid eating and drinking in a working environment influenced by biological hazard factors;
  • Provide the employees with adequate working clothes; in the case of employees working in the area of 3rd and 4th grade      hazards, provide employees also with protective clothing;
  • Provide employees with shower rooms, antiseptic skin cleaning products and, if required, install also eye washing showers;
  • Guarantee that all used personal protective gear is cleaned and checked at the end of the workday; that they are stored in the agreed      place and that the defective means are fixed or replaced prior to their next use;
  • Determine the handling order of materials or samples of human or bestial origin.

If the contamination of working and protective clothing with biological hazard factors during the work process is likely, these must be taken off when leaving the work area and kept in specially marked containers, separately from other clothing, until washed and cleaned.
