OHCT Services

Operations involving high air temperatures, radiant heat sources, high humidity, direct physical contact with hot objects, or strenuous physical activities have a high potential for inducing heat stress in employees engaged in such operations. OHCT Services will assist your company in the development of a Heat Stress Program to include the evaluation of heat stress levels and the employees work practices to minimize the effects.

OHCT Services uses state of the art equipment and technology, to evaluate a broad range of air quality parameters in the building environment. Real time instrumentation, with data logging capability, allows detailed investigation of daily variations in building air quality. From basic thermal comfort parameters such as temperature and humidity through to potential atmospheric contaminants such as carbon monoxide, carbon dioxide, VOCs – OHCT Services can provide assessment of indoor air quality and practical recommendations for ensuring ‘healthy buildings’.

Every employer shall cause every workplace in his undertaking to be lighted in accordance with the illuminance values specified in OSH Act Environmental regulations: Provided that where specialised lighting is necessary for the performance of any particular type of work, irrespective of whether that type of work is listed in the Schedule or not, the employer of those employees who perform such work shall ensure that such specialized lighting is available to and is used by such employees.

Maintenance of thermal comfort is important to ensure a safe, healthy and productive workplace. When the temperature becomes too cold, employees start to experience discomfort of a subjective nature, but eventually may experience physical problems that impair health and productivity. Every employer should have a Heat and/or Cold Stress Survey conducted at their premises as required in terms of Sections 2(1) and 2(4) of the Environmental Regulations for Workplaces.

OHCT Services will provide a comprehensive Data Collection, Verification and Reporting Service that complies with National. Environmental Management: Air Quality Act 39 of 2004 (NEMAQA) requirements

In terms of the South African National Standards – (The measurement and rating of environmental noise with respect to land use, health, annoyance and to speech communication – (SANS 10103:2004)) noise levels at the perimeter of any factory may not exceed certain values and depend on the area (CBD, industrial, rural, suburban etc.) and on time (day, night or weekends).

Asbestos air monitoring tests for respirable asbestos fibres in the air to assist in assessing exposure and the effectiveness of control measures. This is generally undertaken where asbestos containing products are in a poor condition, potentially liberating asbestos fibres into the air, or where asbestos containing materials are being removed. For the purposes of asbestos air monitoring, only respirable asbestos fibres (those fibres less than 3 μm wide, more than 5 μm long and with a length to width ratio of more than 3 to 1) are considered to be a risk.

If your workplace exposes employees to loud noise for extended periods of time, it’s important to have a noise management plan in place to minimise risk while complying with Workplace Noise Regulations. Exposure to noise in the workplace is one of the leading causes for workers’ compensation claims. Protecting employees through an adequate noise management plan can reduce and even eliminate claims by measuring workplace noise exposures and ensuring that there are adequate, documented controls to ultimately conserve hearing.
