Any job that involves working on heights is very risky. A number of accidents occur while workers are on a ladder; some of these accidents have led to death or serious injuries. According to the General Safety Regulation 6 of the Occupational Health and Safety Act (Act 85 of 1993), no worker may work above ground level unless they use a ladder. Work from an elevated position is dangerous enough; imagine standing on a faulty ladder.
To avoid injuries and the financial burden of workplace accidents, you need to invest in quality heavy duty ladders that are reliable; additionally, you need to make sure that you maintain them so that they can always be ready for use.
