A workplace must be planned, constructed, used and maintained to protect from danger any person working at the workplace. The employer must ensure that each building and temporary or permanent structure in a workplace is capable of withstanding any stresses likely to be imposed on it. If this Regulation requires an operation or maintenance manual for a tool, machine or piece of equipment, the employer must ensure that before the tool, machine or piece of equipment is used in the workplace.
If machinery, equipment or a structure is dismantled in whole or in part, and subsequently re-assembled, it must be checked by a qualified person and determined to be safe before operation or use. If a machine or piece of equipment has a rated capacity which varies with the reach or configuration of the machine or equipment, or has other operating limitations,. Before any equipment, machinery or work process is put into operation the persons responsible for doing so must ensure that.

A person must not intentionally remove, impair, or render ineffective any safeguard provided for the protection of workers, except as permitted by this Regulation. If work activities conducted by or on behalf of an employer cause a utility service to be hit or damaged, the employer must notify the owner of the utility service without delay. Note: In the application of sections 4. There is a need for disclosure of potential impairment from any source, and for adequate supervision of work to ensure reported or observed impairment is effectively managed.
In sections 4. Note: High risk activities require shorter time intervals between checks.
The preferred method for checking is visual or two-way voice contact, but where such a system is not practicable, a one-way system which allows the worker to call or signal for help and which will send a call for help if the worker does not reset the device after a predetermined interval is acceptable. A worker described in section 4. The procedures referred to in sections 4. Note: Worker means a worker as defined under the Workers Compensation Act, and includes a supervisor or other representative of the employer see Part 3, Division 1, section A person must not engage in any improper activity or behaviour at a workplace that might create or constitute a hazard to themselves or to any other person.
Improper activity or behaviour must be reported and investigated as required by Part 3 Rights and Responsibilities. If a risk of injury to workers from violence is identified by an assessment performed under section 4.
Note: The requirements for risk assessment, procedures and policies, the duty to respond to incidents and to instruct workers are based on the recognition of violence in the workplace as an occupational hazard. There must be a safe way of entering and leaving each place where work is performed and a worker must not use another way, if the other way is hazardous. Hazardous areas not intended to be accessible to workers must be secured by locked doors or equivalent means of security, and must not be entered unless safe work procedures are developed and followed.
A worker must not be permitted to enter or work in an area if visibility in the area is restricted by the presence of smoke, steam or other substance in the atmosphere, unless appropriate safe work procedures are followed. If a work process results in a liquid accumulating on the floor or grade surface in a work area and the liquid creates a slipping or other hazard, floor drains or other suitable means must be used to control the hazard.
Refuse, spills and waste material must not be allowed to accumulate so as to constitute a hazard. A worker must not enter or remain in any place where there is a danger of entrapment or engulfment in loose materials or from other circumstances unless. Note: See Part 9 Confined Spaces for requirements to control the risk of entrapment or engulfment in a confined space.
An area in which material may be dropped, dumped or spilled must be guarded to prevent inadvertent entry by workers, or protected by adequate covers and guarding. The purpose of sections 4. Click here to Expand all. Click here to Collapse all.

View Section, 7. View Section, 8. Braking is automatically applied to individual wheels, such as the outer front wheel to counter oversteer, or the inner rear wheel to counter understeer. The stability control of some cars may not be compatible with some driving techniques, such as power induced over-steer. It is therefore, at least from a sporting point of view, preferable that it can be disabled.
Of course things should be the same, left and right, for road cars. Camber affects steering because a tire generates a force towards the side that the top is leaning towards.

This is called camber thrust. Additional front negative camber is used to improve the cornering ability of cars with insufficient camber gain. The frame may flex with load, especially twisting on bumps. Rigidity is considered to help handling. At least it simplifies the suspension engineers work. Some cars, such as the Mercedes-Benz SL have had high doors to allow a stiffer frame. Handling is a property of the car, but different characteristics will work well with different drivers.
The more experience a person has with a car or type of car the more likely they will be to take full advantage of its handling characteristics under adverse conditions. In a similar manner, a lack of support for the seating position of the driver may cause them to move around as the car undergoes rapid acceleration through cornering, taking off or braking. This interferes with precise control inputs, making the car more difficult to control. Being able to reach the controls easily is also an important consideration,  especially if a car is being driven hard.
In some circumstances, good support may allow a driver to retain some control, even after a minor accident or after the first stage of an accident. Weather affects handling by changing the amount of available traction on a surface. Different tires do best in different weather. Deep water is an exception to the rule that wider tires improve road holding. See aquaplaning under tires, below. Cars with relatively soft suspension and with low unsprung weight are least affected by uneven surfaces, while on flat smooth surfaces the stiffer the better.
Unexpected water, ice, oil, etc.

When any wheel leaves contact with the road there is a change in handling, so the suspension should keep all four or three wheels on the road in spite of hard cornering, swerving and bumps in the road. It is very important for handling, as well as other reasons, not to run out of suspension travel and "bottom" or "top". It is usually most desirable to have the car adjusted for a small amount of understeer , so that it responds predictably to a turn of the steering wheel and the rear wheels have a smaller slip angle than the front wheels.
However this may not be achievable for all loading, road and weather conditions, speed ranges, or while turning under acceleration or braking. Ideally, a car should carry passengers and baggage near its center of gravity and have similar tire loading, camber angle and roll stiffness in front and back to minimise the variation in handling characteristics.

A driver can learn to deal with excessive oversteer or understeer, but not if it varies greatly in a short period of time. Ride quality and handling have always been a compromise - technology has over time allowed automakers to combine more of both features in the same vehicle. High levels of comfort are difficult to reconcile with a low center of gravity, body roll resistance, low angular inertia, support for the driver, steering feel and other characteristics that make a car handle well.
For ordinary production cars, manufactures err towards deliberate understeer as this is safer for inexperienced or inattentive drivers than is oversteer.
