SHEQ Practitioner Ventilation

Job Responsibilities:

SAFETY, HEALTH, ENVIRONMENT AND QUALITY:

• Identify and assess level of continuous risk exposures in area of responsibility by considering exposures to business, financial, legal issues, people, equipment, material, environment, processes, etc.

• Consider the level of risk, apply mitigation, and implement control measures for residual risk (set objectives, minimum requirements, etc.)

• Comply with SHEQ requirements (SHEQ Toolbox)

• Utilise the Integrated Management System (IMS) to initiate, investigate and report SHEQ status.

CUSTOMERS:

• Ensure Customer Satisfaction

BUSINESS PROCESSES:

• Mine Health and Safety Act, 1996 (Act No.29 of 1996) safety and health standards are maintained

• Co-ordinate an Occupational Hygiene programme

• Measure environmental stresses and take corrective actions.

Ventilation:

• Test for harmful pollutants by means of approved handheld electronic instruments and detector tubes

• Determine the cooling power and low air velocities by means of a wet kata thermometer

• Determine the pressure difference between two points in a ventilation system by means of a manometer

• Measure velocity pressures by means of a pitot tube to determine air velocity and volume flow rates

• Construct frameworks and install ventilation doors and brattices to control airflow underground.

• Auxiliary axial flow fan/s, ducting and supplementary ventilation controls.

• Measure and design ventilation requirements.

• Ensure the correct installation

Dust:

• Prepare, implement and coordinate a personal gravimetric dust sampling programme and calculate dust exposure risk

• Issue and retrieve a Dust-Sampling Train

• Determine the dust mass on dust sampling filters

• Collect water samples for analysis of dust and chemical content

• Design a dust and/or fume extraction system and measure to ensure adequate velocity & or quantity of airflow/extraction.

Noise:

• Determine personal equivalent noise exposure levels by means of an integrating-type dosimeter.

• Conduct routine inspections on percussion rock drills and equipment with possible risk of high noise exposure for compliance with the requirement of the Mine Health and Safety Act.

• Measure noise levels in a workplace by means of a sound level meter.

• Measure noise spectrum of a noise source by means of an octave band frequency analyser.

• Ensure all high-risk noise equipment is identified and demarcated as per procedure.

Illumination:

• Measure illumination levels in a workplace by means of a luxmeter.

• Report on illumination results.

Temperature:

• Determine the thermal work environment by means of a wet bulb globe temperature (WBGT) index

• Measure virgin rock temperature.

Pressure:

• Measure compressed air and water pressures by means of a handheld pressure gauge

• Measure barometric pressure by means of electronic and mechanical instruments.

Growth:

• Manage continuous improvement through Operational Excellence
