Mandatory Signs tell people what action they must take in a particular area. They are commonly used to communicate requirements involving personal protective equipment, hygiene, pedestrian routes, machinery and safe working procedures.

At The Sign Shed, we supply a wide range of Mandatory Safety Signs for factories, warehouses, construction sites, workshops, commercial kitchens, schools and other business premises.

Whether you need a single Wash Hands Sign, instructions for a production area or mandatory PPE notices across several entrances, choosing the right message helps make workplace requirements clear.

What Do Mandatory Signs Mean?

Recognised mandatory safety signs normally feature a white pictogram inside a blue circle.

This design indicates an action that must be carried out.

Examples include Wear Eye Protection, Safety Footwear Must Be Worn, Wash Hands and Pedestrians Must Use This Route.

Mandatory signs are different from warning signs, which identify hazards, and prohibition signs, which identify actions that are not permitted.

Mandatory PPE Signs

Personal protective equipment signs communicate requirements to wear specific protection in designated areas.

Common examples include:

• Safety Helmets Must Be Worn.
• Eye Protection Must Be Worn.
• Ear Protection Must Be Worn.
• Safety Footwear Must Be Worn.
• Protective Gloves Must Be Worn.
• High Visibility Clothing Must Be Worn.

The correct instructions depend on the hazards identified and the protective equipment required.

Wash Hands & Hygiene Signs

Mandatory hygiene signs communicate actions such as washing or sanitising hands.

They may be useful in commercial kitchens, food preparation areas, washrooms, healthcare facilities and other workplaces with hygiene procedures.

Choose wording that reflects the actual requirements at the location.

For example, a Wash Hands Sign and a Hand Wash Only Sink Sign communicate different instructions.

Pedestrian Route & Access Instruction Signs

Mandatory pedestrian signs help identify routes that people are required to use.

They may be suitable in warehouses, distribution centres, factories and construction sites where pedestrian movement needs to be managed.

Signs should support appropriate traffic management arrangements, including suitable separation from vehicles where necessary.

Machinery & Equipment Instruction Signs

Some mandatory notices communicate operational requirements around machinery or equipment.

Examples may include keeping guards in position, keeping equipment locked or following particular operating procedures.

These signs should support suitable guarding, maintenance, training and safe systems of work.

A mandatory instruction does not replace the need for appropriate engineering controls.

Mandatory Signs for Construction Sites

Construction sites may require a combination of mandatory instructions, warning signs and access restrictions.

Examples include hard hat requirements, high-visibility clothing instructions, safety footwear notices and designated pedestrian routes.

Choose signs according to the site's risk assessment and the requirements applying to each work area.

Mandatory Signs for Warehouses & Factories

Warehouses and factories may require mandatory notices near vehicle routes, machinery, production areas and designated work zones.

Relevant messages can include Wear Safety Footwear, Wear Eye Protection, Use Pedestrian Route and other site-specific instructions.

Where several instructions apply, a combined sign may be useful, provided the messages remain clear and easy to recognise.

Choosing Mandatory Sign Sizes & Materials

Self-adhesive vinyl signs may be suitable for compatible smooth, clean surfaces such as doors and equipment panels.

Rigid plastic signs may be appropriate for walls, entrances and other mounted applications.

Selected products are also available in materials including recycled plastic, Foamex and aluminium composite.

Choose the sign size according to the viewing distance, lighting and mounting position. Check individual product specifications for available materials and dimensions.

Where Should Mandatory Signs Be Displayed?

Mandatory signs should be positioned where people can recognise the instruction before they need to act.

Suitable locations may include:

• Entrances to PPE-required areas.
• Production and workshop entrances.
• Designated pedestrian routes.
• Hygiene stations.
• Machinery access points.
• Construction site access points.
• Other locations where a particular action is required.

Signs should remain visible and should not be obscured by equipment, stored materials or other notices.

Mandatory Signs & UK Safety Regulations

The Health and Safety (Safety Signs and Signals) Regulations 1996 require appropriate safety signs in relevant workplace circumstances where significant risks remain after other necessary control measures have been taken.

BS EN ISO 7010 includes recognised graphical symbols for many mandatory safety instructions.

However, not every instruction notice uses a standardised ISO 7010 symbol, and displaying a mandatory sign does not automatically establish legal compliance.

Mandatory signs should support appropriate risk assessments, protective measures, training and safe working procedures.
