Signs are used to prevent accidents. They are common in the work area, along the roadside, and in public buildings. OSHA has some specific requirements for signs. The requirements are in place to make sure hazard warnings are easy to recognise and don`t vary from workplace to workplace. This Safety First Topic takes a look at different types of signs; what they mean, and how they should be used.

OSHA defines signs as “the warnings of hazard, temporarily or permanently affixed or placed, at locations where hazards exist.” Danger signs must only be used where an immediate hazard exists. Their appearance is specified by OSHA. These signs are red, black (or contrasting colour), and white with room for words or symbols to describe the danger. Danger signs are common in areas where high voltages exist and where automatically-starting equipment is in use. You may be aware of other hazards which warrant the use of a danger sign.

Warning signs are orange with black (or a contrasting colour) lettering or symbols. They are used to warn against hazards which are not quite as serious as those requiring a danger sign-but are more serious than those requiring a caution sign. Warning signs may alert us to forklift traffic or similar hazards.

Caution signs must be used only to warn against potential hazards or to caution against unsafe work practices. Caution signs are predominately yellow with a black (or contrasting colour) panel at the top of the sign. The word “caution,” written in yellow appears on the panel. The lower part of the sign is used for additional wording which must be written in black (or a contrasting colour). Caution signs warn of numerous hazards-everything from slippery floors to reminding us to wear safety glasses. Even traffic signals take a cue from the yellow caution sign as they warn us to be careful on the road.

Special signs are used just for biological hazards and radiation hazards. The biological hazard (biohazard) sign is fluorescent orange or orange-red with letters or symbols in a contrasting colour. The biohazard sign alerts us to the presence or potential presence of blood or other biological hazards. Radiation hazards are identified with a sign bearing the familiar three-bladed radiation symbol in black or magenta or red on a yellow background.

Safety instruction signs are used to provide information about safety. They are not used to warn against specific hazards. These green and white signs remind you to report accidents, help locate first-aid equipment, and direct you along an evacuation route.

Though signs are never a substitute for good safety procedures and training, they are useful to remind us of hazards and ways we can protect against them. Always take seriously the information on a sign-whether in the workplace or on the road. Understanding signs and the hazards they warn us about can help prevent injuries and save lives.

Battery Electric Tugs Improved Efficiency 40% for MPTTC Company in Australia.

Electric Tug

MPTTC Co is a speciality heavy industry manufacturer in Australia that wished to solve some material handling and safety issues.

They primarily supply equipment to mining companies who demand heavy-duty equipment for their applications.

MPTTC is able to engineer and improve their mining products by using a new heat treatment process to enhance the mechanical attributes of their products.

Mark Jackman, Engineering and Safety Manager at MPTTC , worked with an ​ Australian company that provides and distributes electric tugs, Alitrak Australia.

He advised them that “Loading and handling the bulky equipment in to and out of the furnace is a demanding tasks which involve the manual manoeuvring of heavy industrial trolleys’’. We have been looking to enhance our loading systems for some time, not only to advance health and safety but to remove the manual requirement for operators for moving those heavy and dangerous trolleys.”

By using a battery electric powered tug, MPTTC workers were able to increase the number of trolleys they could load from three at a time to four. Additionally, the equipment allowed the personnel to avoid​  having to approach​close to​the furnace and other heat treatment equipment.

This solution addressed the risks involved with manual handling of material and brought efficiencies in the process, resulting in about 40% increase in output.

The tug worked so well that the company also purchased another series of tugs to replace their traditional waste management system with a new economic and functional solution provided by Alitrak Australia’s expert technical team.

The purchase of additional electric tugs is something Alitrak Australia sees a lot. Versatility is one of the primary benefits of electric powered tugs.

When companies see how well the equipment works on one issue, they can use the equipment on​many​other applications, replacing the manual labour​r system with Alitrak Electric Tugs, spares personnel the physical strain and risk of injury associated with pushing and pulling heavy equipment.

It also allows employees to get more done, which increases efficiency considerably.

If your job includes strenuous pushing or pulling tasks, it can be enhanced with a battery electric tug.

Keep your industrial workers safe with traffic control systems


With so many powered industrial vehicles whizzing around warehouses, distribution centers and ports, the threat of an accident involving a truck or forklift is always present.

However, with the right traffic control systems in place, businesses can significantly lower the chances of employee injury related to such accidents.

The most common powered industrial vehicle accidents occur when forklift drivers inadvertently travel too far and fall off the edge of loading platforms.

Other common accidents include backover injuries, those that occur when employees fail to secure rigs to loading platforms and when large vehicles tip over.

While employee safety will always be best with the right training, there are plenty of products you can use to make your workplace the safest environment possible.

For example, Tru-Gard Bollards are a great way to protect your facility, assets and workers from industrial vehicles. These items are most commonly used to protect pallet racking, door tracks and the corners of walls. If necessary, these poles can be fixed into concrete for heavy duty mounting.

There are also removable options that can be set in front of entrances and doors to protect employees.

However, such durable equipment isn’t always necessary. In certain cases, it may be better to use a Veriflex KnockDown sign or post mounting system. These require no internal cables that can fray or snap, and can be easily installed anywhere in a workplace.

These often include Stop or Give Way signs that if struck won’t be damaged, but rather will flop down and spring back up.

Other items you may want to consider to improve warehouse safety include pedestrian barriers,impact absorbing technologies, speed humps and machine guarding systems.
