Diving should be avoided during pregnancy.

Whole body vibration

Regular exposure to whole-body vibration or shocks, e.g. from off-road vehicles, is inadvisable for pregnant workers.


Potential risks
New and expectant mothers are particularly vulnerable to stress and the risk assessment should take account of organisational stressors.

Control measures
Control measures may include:

  • adjustment of working conditions/hours where necessary;
  • ensuring individuals have opportunities to raise concerns;
  • ensuring concerns are appropriately dealt with;
  • referral to the Occupational Health Service where required.

Manual handling           

Potential risks
Hormonal changes may affect ligaments making them more susceptible to injury and postural and dexterity problems increase as the pregnancy develops.

Control measures
Line managers should re-assess the risks with regard to manual handling tasks associated with the work activity and look to avoid or reduce manual handling tasks undertaken by the new or expectant mother.

Lone working and working out-of-hours

Potential risks
Risk assessments should be reassessed with the individual with regard to lone working or out-of-hours working, particularly for procedures for summoning emergency medical assistance.

Control measures
Review risk assessments, including emergency measures; the Occupational Health Service may be consulted for advice on work patterns which may impact on the health of the expectant mother, such as excessive fatigue, insufficient rest etc.

Violence and aggression

Potential risks
Physical violence can result in severe injury to both the expectant mother and the unborn child; activities should be assessed to determine the level of risk from potentially confrontational situations.

Control measures
Consideration should be given to avaoiding exposure to aggression or perceived threat of aggression.
