Health and Safety Hygiene Surveys

Occupational Health and Safety Hygiene Surveys in the Workplace

Employers in South Africa are required to ensure that the work environment is free of risks to the health and safety of employees and visitors to the premises. To ensure that this is done, employers are required to assess the exposure that their employees have to hazardous environmental conditions.

This can be done effectively by carrying out occupational hygiene surveys, health and safety hygiene surveys, and overall workplace surveys. While the employer is the ultimate responsible party to ensure this, they can employ the services of a competent person who is trained and certified Approved Inspection Authority to carry out these health and safety surveys in the workplace.

If there is an Risk Assessment that indicates consistent risks from exposures, employers are obligated to have these exposures measured so that the results can be compared to prescribed health and safety standards.

MAKROSAFE has been assisting clients for more than 24 years.

The next step to follow, after the health and safety survey, is to implement the necessary steps to limit exposure according to the Occupational Health and Safety Act 85 of 1993. This process is also referred to as monitoring and it requires approval and verification from an Approved Inspection Authority.

The importance of hygiene surveys cannot be emphasised enough, with the health and safety of employees as a top priority of any organisation or employer, which is why the International Organisation for Standardisation developed ISO 45001, Occupational Health and Safety Management Systems.

It is impossible to predict when a workplace event may occur. Even while it is difficult to eliminate the possibility of an unanticipated accident, it is within the power of South African company owners to reduce the chance of workplace injuries.

Many industrial sites have different equipment, chemicals, and tools that employees must use to carry out their duties, and they are exposed to certain hazards regularly and reducing the dangers they confront could help keep workplace injury rates low.

The occupational hygiene assessment is a thorough study of the dangers in the workplace that might endanger workers. It enables the employer to assess risks and evaluate if enough safeguards are in place to protect your personnel.

Accidents and illness have the potential to destroy lives. It may also harm the overall company by reducing productivity, causing mechanical damage, and driving up insurance costs.

The following are some of the laws that apply to workplaces in South Africa to meet occupational hygiene standards:

  • Section 8 of the Occupational Health and Safety Act 85 of 1993
  • Section 5 of the Hazardous Chemical Substances Regulation of 1995
  • Section 6 of the Noise-Induced Hearing Loss Regulation of 2004.

Who Conducts a Hygiene Survey?

To assist companies in complying with South African standards relating to Health and Safety Hygiene Surveys, legislation mandates that surveys and evaluations be done by an Approved Inspection Authority.

In every workplace, employers must implement a thorough Occupational Hygiene Program that clearly defines and indicates the different responsibilities of persons who must be involved. The Occupational Hygiene Program must consist of these components:

  • Commitment of the organisation
  • Occupational Hygiene Survey Process
  • Roles and Responsibilities

The process involved with a Hygiene Survey include:

  • Hazard Assessment
  • Determining the Level of Risk
  • Level of control over the risk
  • Walkthrough Survey
  • Exposure assessment
  • Determine the level of exposure
  • Implement controls
  • Indicate any additional assessments on exposure
  • Implement monitoring schedules

Hygiene Surveys

Hazard Assessment

When a chemical, biological, or physical danger is detected on the hazard assessment, the occupational hygiene procedure is initiated.

Determining the Level of Risk

The hazard assessment must be conducted by a competent person and include a qualitative assessment of the risks which are connected to the identified occupational hygiene hazard.

The possible health impacts that might occur from the amounts utilized and the period of exposure are considered to determine whether the risk level is acceptable. Further action is necessary if the substance/agent provides an unacceptable danger or if the risk level is uncertain.

Level of control over the risk

If controls can be implemented to control the risk, it must be done according to legislative requirements. If controls can be implemented to mitigate the risk their effectiveness must be verified and/or monitored to ensure that the process can be completed.

If a hazard cannot be controlled or there are specific regulatory requirements that demand it, a walkthrough survey must be carried out. In addition, walkthroughs are necessary when the controls that have been implemented are not effective.

Walkthrough Survey

If further investigation is necessary, a walkthrough must be carried out with the responsible supervisor or manager in the area where the hazard has been identified. The walkthrough survey must note the following:

  • The name of the department where the hazard was identified along with the specific process
  • The name of the operation
  • The raw materials being used and their quantities
  • The equipment and machinery used to carry out the task
  • The health hazards that were identified and the routes associated with exposure
  • The current controls that are in place
  • The number of workers who are exposed and their specific positions
  • The items that must be followed up after the hygiene survey

Exposure Assessment

When the walkthrough has been carried out, the information that was collected can be used to determine the level of worker exposure. The quantitative evaluation of exposure will need a level of monitoring, which will be determined by the following factors:

  • The duration of exposure
  • The number of workers in the area that are exposed to the same risk
  • The sampling methods that are currently being used and their limitations
  • The degree of accuracy that is required in the results obtained
  • The number of samples that must be collected to achieve representative results
  • The cost
  • The regulatory requirements

Determine the level of exposure

To determine whether the level of exposure is acceptable the Occupational Exposure Limits, or OELs must be used alongside approved occupational hygiene practices as well as professional judgment. This determination can be guided by an action level, or the point at which hazard controls are recommended and set at 50% of the OEL, especially where historical data is not readily available.

However, if adequate historical data is available, action levels can be determined using the approved and current occupational hygiene practices.

Hygiene Surveys

Implement controls

The hierarchy of controls must be considered when new controls are implemented for the identified and assessed hazards. Engineering controls must always get preference followed by administrative controls and then personal protective equipment (PPE).

The hazard controls must be implemented by the supervisor or manager of the department and the Occupational Hygiene Consultant must be notified in writing of such implementation.

Indicate any additional assessments on exposure

A crucial process revolves around evaluating the effectiveness of controls, which will require a monitoring strategy as well as a schedule. If there are new processes, equipment, or products introduced into the workplace additional exposure assessments must be carried out.

Implement monitoring schedules

When substances or agents cannot be eliminated in the workplace a monitoring schedule must be developed. These must indicate the following:

  • The specific agent or substance to be monitored
  • The frequency of monitoring
  • How the monitoring will be carried out

List of Hygiene Surveys
