The emergency stop button must be located at convenient location which should be easily
identifiable and provide with markings for clear marking so that it can be easily accessible.
Activating emergency stop button must bring the machine to safe position, disengaging
emergency stop button must not restart the machine, restarting should only be the command
from main panel by the operator.

Stability
The equipment must be fixed and secured in one position to prevent unintentional movement
during operation. Machineries can be fixed on the floor using nuts, blots & clamps; in case of lifting
equipment for e.g. Cranes, it is controlled with outriggers, additional precautions may be.

Lighting

The lighting must be adequate for the task to be carried out, in some areas, there may be local
lighting for workstation may be necessary, consider special lighting for flammable atmosphere.
Local lighting shall not produce glare, any stroboscopic effects.

Lighting levels should be checked periodically to ensure that the intensity is not diminished by
dust and grime deposits.

Markings

The work equipment should be clearly marked with warnings. Warnings and markings include:

• Operating instruction
• Hot surface
• Radiation hazards

• SWL safe working Load marked for lifting equipment
• Maximum and minimum operating speed for grinding machine, cutting machine

• Entanglement hazard
• Ejection hazard – flying objects, sparks.

Marking can be in the form of shapes, graphical pictogram, words – instruction.

Warnings
Alarms and flashlights can be used to alert people prior to machine start to keep people away
from danger. E.g. Audible and flashlight alarms alerts people prior to conveyor belt operation start.
Consider environmental condition for lightings, poor lighting may obstruct visibility to the visual
warnings. Noisy atmosphere can impede audible alarms; hence it is not suitable for noisy
atmosphere.

Clear Unobstructed Workspace

Unobstructed space allows the operator to move around the machinery also to carry out the task
safely. The work area must be wide enough without any obstructions to move around or carry out
pre-user checks. The work area must be provided with safe access, any obstruction must be clearly
marked, if there is lifting operation carried out then the area must be clear off from obstruction,
all unwanted materials must be cleared at regular intervals.
