Environmental VOC monitoring

SURVEY TYPE: ENVIRONMENTAL VOC MONITORING

DESCRIPTION & DETAILS: The survey will be conducted to quantify the levels of volatile organic chemicals (VOCs) at predetermined sampling points along the boundaries.

LEGISLATION

Department of Environmental Affairs and Tourism (DEAT) Guidelines

DEAT does not have any average monthly guideline limits for non-methane hydrocarbons. Thus use is made of the threshold limit values (TLV’s) as published by the American Conference for Governmental Industrial Hygienists (ACGIH). The guideline limit is taken as 1/50th for ordinary pollutants and 1/100th of the TLV for carcinogenic or suspected carcinogens.

SAMPLING PROCEDURE

The Radiello is the ambient method of choice for non-methane organic hydrocarbons. Sample collection is taken over a 30-day period.

 

 

Lead Chemical Stressors

SURVEY TYPE: LEAD MONITORING

DESCRIPTION AND DETAILS: Personal and ambient Tetraethyl Lead (TEL) air monitoring will be carried out to establish exposure levels of Tetraethyl Lead

LEGAL REQUIREMENT AND STANDARDS

The survey will be carried out in accordance with the Occupational Health and Safety Act, Act 85 of 1993 – Lead Regulations.

LEAD REGULATIONS

“Occupational exposure limit for lead, in the case of tetraethyl lead”, means an exposure limit of
0.10 mg lead per cubic meter of air, measured in accordance with the health and safety standard.

SAMPLING METHOD: Tetraethyl Lead – NIOSH 2533

SAMPLING PROCEDURES- Sampling pumps with XAD 2 tubes will be attached within the breathing zones of employees identified as highest risk employees and at pre- selected sampling points that represent the concentrations of TEL in the atmosphere.

Ergonomics

Ergonomics is the process of designing or arranging workplaces, products and systems so that they fit the people who use them.

Health Risk Assessments

A health risk assessment (HRA) is a health questionnaire, used to provide individuals with an evaluation of their health risks and quality of life.

Personal Protective Equipment (PPE)

Personal Protective Equipment (PPE) will protect the user against health or safety risks at work. It includes items such as safety helmets, gloves, eye protection, high-visibility clothing, safety footwear and safety harnesses. It also includes respiratory protective equipment (RPE).

Thermal Stress

Heat & Cold: Measurements will be carried out over hourly intervals

Legal requirement and relevant standards

Environmental Regulations for Workplaces R2281:1987

Mechanical Ventilation

Face and Capture Velocity measurements will be conducted on all local exhaust ventilation systems.

Legal requirement and relevant standards

HCS Regulations – Section 12 and Control of Substances Hazardous to Health Regulations.

Control of Substance Hazardous to Health (CoSHH) Regulations.

Ventilation and Indoor Air Quality Survey

Qualitative air assessment will be conducted and/or air movement will be measured in the working areas to ascertain if the working conditions are suitable for the work being performed.

Legal requirement and relevant standards

ASHRAE Standard 62, Ventilation for Acceptable Indoor Air Quality.

ASHRAE Standard 55, Thermal Environmental conditions for human occupancy.

SANS 10400 Part 0: 2011 – National Building Regulations

Lighting Survey

The illumination levels will be carried out in accordance with the SANS 10114 – 1:2005 “Artificial Lighting of Interiors”.

Legal requirement and relevant standards

The results will be compared to the standards provided in the Environmental Regulations for Workplaces R2281:1987
