38Confined Space

A confined space is determined by the structure and a specific set of circumstances. The same structure may or may not be a confined space depending on the circumstances when the space is entered. Entry to a confined space is considered to have occurred when a person’s head or upper body enters the space.

A space may become a confined space if work that is to be carried out in the space would generate harmful concentrations of airborne contaminants.

Activity 1.4Safe Operating Procedure in Confined SpaceCompany A has hired services to re-paint in a confined space. The work is being conducted in a confined space and the work environment in this space contains harmful atmosphere. The safe operating procedure for this space requires that A safe atmosphere can be achieved within the confined space using methods such as cleaning, purging and ventilation. Assume that the atmosphere has been cleared of contaminants. Determine what is cold be missing in this picture.

Organisational Procedures are followed with regards to chemicals

2.1 Functions of chemicals in the workplace are recognised

2.2 Chemical labels and symbols are recognised and hazards identified

2.3 Chemical storage locations are identified

2.4 Instructions for transport, handling and storage of chemicals are recognised

2.5 Instructions for use, maintenance and storage of personal protective equipment and application are identified and observed

[Answer ALL Activities in the Learner Workbook]


392. Recognise Risks Associated with Chemicals

2.1 Functions of chemicals in the workplace are recognised

Generally, MSDS [Section 1]states intended use of the product. Take note that some chemicals may be;

Corrosives

Flammables

Solvents - organic, chlorinated

Explosives

Laboratory agents

Toxic substances

Sensitisers


40

2.1 Functions of chemicals in the workplace are recognised – Hierarchy Control

Eliminate the hazard: Eliminate the dangerous substance or process or replace it by a less dangerous one.

Put distance or shielding between the substance and the worker: Prevent the dangers associated with the chemical from reaching the worker

Ventilation: Provide general and local ventilation to remove or reduce the concentration of airborne contaminants such as fumes, gases, vapours and mists.

Protect the worker: Provide personal protection to the worker to prevent physical contact with the chemical. These principles are discussed in detail below.


41

The use of PPE as a sole risk control or even PPE and Administrative Controls is a STOP (not acceptable)

Engineering controls including isolation may be acceptable but must be used with caution

Elimination and Substitution are the control options of choice and must be considered

Please give two examples of Corrosive materials. [You may refer to the user manual or by using the Chemwatch application tool]. Fill in the Learner’s Workbook provided by the trainer with your answers.

Please explain the term “Flashpoint”. [You may refer to the user’s manual. Fill in the “Learner’s Workbook” provided by the trainer with your answers.

60Segregation

ClassSegregation Guidance Notes

S1 Segregate these goods by 3m or more in a well-ventilated area. For liquid dangerous goods the distance is measured from the edge of the spill catchment area. See supplementary notes 6 and 7.

S2 Segregate by 5 m or more. If one of the dangerous goods is a liquid, measure the distance from the edge of the spill catchment area. Liquid dangerous goods should be located within a separate spill catchment area. See supplementary notes 6 and 7.

S3 Segregate by 3 m or more for PG III goods and 5m or more for PG II, PG I goods or where the goods may react dangerously. If both are solids then a minimum of 1m separation may be used. Where one of the goods is a liquid the distance is measured from the edge of the spill catchment area. See supplementary notes 6 and 7.

S4 Segregation preferred by the use of fire-rated partitioned areas. Consider use of separate detached building for organic peroxides and for highly pyrophoric class 4.2 goods.

S5 Segregation of class 4.3 preferred by use of a separate, detached building without water based fire suppression system.
