1990, CHAPTER O.1 PART III.1; 32.1-32.4). The plant is covered under the Industrial Establishment regulation of the OHS act (R.R.O. 1990, Reg. 851, s.3.). The Ontario act and the regulations for industrial establishment
The plant has an open layout. The layout is segmented into various sections where specialized work is carried out. The circular saw is located in the carpentry and joinery section. Although the plant employs 50 workers, only about 10 employees are trained in the use of the circular saw.
The circular saw used is an electrically powered saw. It uses its own electrical outlet and cannot be operated by any other means. It was first installed about 8 years ago by the manufacturers and is fully owned by the company. There are 5 circular saws in the work area; two are with radius of about 10 inches and the others about 8 inches in diameter. The circular saw has procedures of use that details maintenance time-lines, hours of operation and troubleshooting. Above all the designers and manufacturers have outlined in the operation manual that only authorized persons should operate the equipment. The manufactures have also suggested a restricted work area.
(i) Pre-use: there is no operational checklist prior to use of the circular saw. ...
(i) The area is not clearly marked as a restricted area. Un-authorised personnel usually occupy it.
(ii) The work area is not clear of debris such as dust and wood chips. The sanitation and maintenance is performed at the discretion of the operators, usually after long periods.
(b) Employee Training
The manufacturers (designers) have provided training manuals for the equipment. However,
(i) Newly assigned workers including temporary workers do not receive the prescribed level of training before operating the saw.
(ii) Workers from other sections of the plant frequently use the saws without training or supervision.
(iii) Training updates on use of the saw is not scheduled for any of the workers.
(iv) The manuals of operation for the section (including for circular saw equipment) are not in full display therefore are hardly referenced by employees.
(c) Maintenance of Equipment
Regular and periodic maintenance is prescribed by the manufacturer of the circular saw. The assessment of the equipment maintenance is as follows:
(i) Pre-use: there is no operational checklist prior to use of the circular saw. Therefore the saw is not always checked for lodged bits and chips stuck under the blades. The saw is not checked for performance before use e.g. there is no testing of emergency stops.
(ii) Post-use: Debris from operating the saw is not cleared from away. Guards are not always deployed to restrict blade movement during cleaning. Electrical power is not turned off during post operation use.
(iii) Manufacturers have completed a scheduled maintenance of the equipment.
(d) Personal Protective Equipment (PPE)
The use of PPE is left to the discretion of the workers. An assessment revealed the following non-compliance:
