No Trespassing Caution Signs for Work Sites

ANSI Caution Sign for Trespassing

Property signs like no trespassing signs are typically used to express a landowner’s private policy, and are not subject to compliance with ANSI or OSHA sign standards. These signs can be any color, size, shape, and have any message. The most popular no trespassing signs are simple, with basic colors such as red, white, or black, which can be seen at a great distance and are highly noticeable when posted at the edge of a property or on a fence.

Construction sites and other work sites will post no trespassing signs as well, but often only to keep unauthorized persons off of the property. Due to the types of hazards usually found at a construction work zone, if the no trespassing signs have an ANSI / OSHA design and signal word, it would likely be a “danger” sign.

Since the “danger” signal word should only be used when the risk of death or serious injury will probably occur, if may not be the most accurate in all applications. When moderate or minor injury may occur, the use of a caution sign could be more fitting. No trespassing caution signs may be a better fit for zones where there may be trip hazards, forklift traffic, or other considerable hazards where trespassing should be stopped.

Only the user of a sign, who is best familiar with a specific hazard, can properly evaluate and assess the need for the use of no trespassing caution signs, along with the proper sign size, viewing distance, position, and other important factors.

By adding the caution sign header and safety symbol to no trespassing signs, property owners are able to protect their property and meet workplace signage compliance regulations at the same time. The addition of the “caution” signal word adds significance to the safety message of a trespassing sign, which most passers-by recognize simply as a property sign.

OSHA Required Caution Signs

Electrical panel signs designed as caution signs and danger signs are necessary to remind workers that the area around the panel has to stay clear. OSHA (Occupational Safety and Health Administration) requires that facilities keep the area in front of electrical panels clear for at least 36 inches. Caution signs bring attention to this important safety concern when serious danger is not present.

Keeping your electrical panel clear is important because it makes working on the panel much easier, especially in an emergency. Having easy access to the panel gives your staff the time that they need to flip switches and get to the breakers, which reduces the time before power surges or faulty machine wiring does serious damage.

By keeping this area clear, the risk of conducting electrical current to nearby objects is also cut down. If the panel is not properly wired, and metal ladders, poles, or other materials that conduct electricity are nearby, workers using those pieces of equipment can be seriously injured, with those injuries possibility resulting in death.

Having a clear area around your electrical panel may also help firefighters. During an electrical fire, if started near the panel, there would be less combustible materials to help the fire spread across your facility if the area is cleared out.

Both caution signs and danger signs, with OSHA approved headers and colors, can be helpful to avoiding these situations. ANSI versions of the danger and caution signs have approved headers and messages, with the addition of easy to understand images that help all workers, regardless of language, to work properly around the electrical panels.

ANSI Standards on Your Pipes

When alerting workers to potential hazard, ANSI caution signs are used in conditions where there is a “moderate to minor injury” risk. ANSI states that the signs should have a yellow header with signal words and symbols written in black to further clarify the hazard.

ANSI also has standards relating to the pipes in your facility. In the ANSI / ASME A13.1 2007 standard, the color combination for industrial pipe markers on pipes that carry flammable fluids is also yellow and black. A safety yellow background with black legend alerts staff and maintenance workers of the potentially hazardous materials that flow in the pipes, which pose a “moderate to minor injury” risk.

Popular legends on yellow “caution” pipe makers are for fuel oil return and supply, natural gas (both general and PSI specific legends), and medical air supplies.

According to the ANSI / ASME A13.1 1996 color scheme, pipe markers with a yellow background and black legend marked pipes carrying materials that are “inherently hazardous.” These include flammable, explosive, chemically active, toxic, and radioactive materials. The newer 2007 standard further breaks these types of materials down into different classifications.

Caution sign size and text size is determined by the location of the sign and its relation to the hazard. Pipe markers can not change in size, as they must match the size of the pipe, so spacing of the pipe markers on the pipe becomes more important, along with the direction that the markers installed.

“Caution” pipe markers are installed close to valves, branches, and anywhere that the pipe changes direction. The pipe should be marked before and after wall, ceiling, and floor passes. For long, uninterrupted runs of pipe, pipe markers should be installed for best visibility, which is typically every 20 feet. The distance can be cut down if pipes run along other piping systems or if visibility is obstructed.

Elevator Caution Signs

Caution Signs for Elevator Capacity and Fire Safety

This week is National Elevator Escalator Safety Awareness Week, when we should all become more aware of the safety procedures concerning the use, maintenance, and repair of elevators and escalators.

Elevator caution signs are useful reminders that elevators are powerful machines, but their power is not limitless. We often take for granted the amount of weight that an elevator can hold and lift up from level to level in a warehouse or other complex. Elevator caution signs like ones stating load capacity help reduce improper use of the machines, effectively preventing unnecessary repairs due to overloading.

Other elevator caution signs include fire safety signs. As elevators have overtaken stairs as the primary method of moving from one floor to another, using the elevator has become second nature to most of us. The signs remind us that the safest path to exit during a fire emergency is always through the stairs. This is a fact that could be forgotten during the panic of an emergency, making these caution signs real life-saving tools.

Elevator caution signs are generally used to post the maximum load capacity in pounds. This is helpful in warehouses and other facilities where large amounts of freight, machinery, and other goods are being moved. Not all elevators are “freight” elevators in warehouses, though. For riders, capacity signs can safely limit the amount of people inside your elevators.

The right caution signs for your elevators depends on your specific use. Whatever your needs and use of elevators, these machines are extremely useful pieces of technology. Without them, the entire architecture of a facility would been to be altered to allow for heavy equipment to either only be used on the ground floor or needing cranes and pulley systems to raise the items up to the desired level.

Halloween Safety Tips

Safety Tips for Your Halloween

halloween caution signReady for Halloween this year? This year’s festivities will be celebrated in a slightly different light than in previous years, as the eastern parts of the United States hope to avoid terrible weather and celebrate the first Halloween since 2010. 2011’s holiday was covered in snow for most, while last year’s holiday was delayed or outright cancelled due to the effects of superstorm Sandy.

As an authority on caution signs and safety, we’d like to refresh your memory and list some important trick-or-treating safety tips.

  • Don’t go out alone. Sure, you might be able to keep the candy all to yourself, but there is safety in numbers.
  • Add reflective tape to costumes and bags to increase visibility to drivers.
  • Accessories (pirate swords, cowboy pistols, princess wands) should be short and soft to avoid injury.
  • Avoid homemade treats and carefully inspect all treats for tampering and choking hazards.
  • Give out healthy treats instead of sugary, high calorie ones.
  • Light a safe path through walking areas and by stairs to reduce chances of trips and falls.

There are plenty more safety tips to practice this Halloween, many of which are practiced everyday. These include safe pedestrian crossing practices, “stranger danger” awareness, and smart eating habits.

If you are hosting a party, offer vegetable plates and low sugar/calorie options so kids don’t overeat candy. Adding some physical activities during the party can liven up the crowd and burn off some of the sugar rush too! Try pinning the nose on the jack-o-lantern or a variation of cornhole where beanbags are tossed into an open, cleaned out pumpkin.

No matter what you end up doing this Halloween, make sure you do three things: 1. have fun, 2. stay safe, 3. be scary.

Happy Halloween!

Caution Hot Labels

Machine Safety Labels Save Your Skin

Caution Signs for Machines

Hot Surface Machine Label

Caution hot surface labels are important machine safety labels in numerous types of industry. Burns are one of the most common types of workplace injury, causing time lost and lowering productivity. Caution hot surface labels are made from high quality, durable materials that are able to stand up to the heat! These stickers can withstand temperatures over 300 degrees Fahrenheit.

Besides the ability to hold up against high temperatures, caution hot surface labels can stick to almost any clean, dry surface; glass, plastic, or metal; flat or curved surfaces. By being able to stick this caution labels anywhere, workers can easily be warned and reminded about the serious risk of injury from heat at the point of danger.

Caution hot surface labels can be applied near personal protective equipment signs and equipment like safety gloves and aprons to reinforce the need to use safety equipment when near the hot parts of machines. The stickers, when applied directly to areas that become hot to the touch, creates a visual reminder that heat is there because the dangerous temperature cannot be seen.

Hot surface labels that comply with ANSI Z535 will have a yellow header and clearly visible lettering noting that you should exercise caution in the area. The exclamation point inside a triangle symbol commonly joins the message. Recommended placement of these labels is at a place clearly visible to those in danger, on or near the hazard. The label needs to be permanently affixed. In addition to caution hot surface labels, small stand up signs or tents are also effective ways to alert workers of hazardous and hot surfaces.

Folding Caution Signs

Caution Signs for Floor Hazards

Folding floor signs, floor tents, floor stands, whatever it is you call them, they all work as caution signs to help alert you of potential hazards. These portable and lightweight signage options are typically seen in stores and supermarkets just after the PA system announces “Cleanup on Aisle 4.” Durable plastic construction and a clear message make these special caution signs the favorite choice for small business owners who only need one or two and are happy to have safety equipment that will last for several years.

Caution signs and floor safety cones are effective ways to alert employees and visitors of a serious but not often thought of hazard – standing water. Whether from a spill or tracked inside from rain or snow, water is a dangerous safety hazard.

Slip and fall injuries are one of the leading causes of missed time at work in the United States. These injuries account for 8.9 million emergency room visits annually (source:

Yellow Road Signs

Road Caution Signs and the Rules of the Road

The Manual on Uniform Traffic Control Devices (MUTCD) is the standard used for all public street signs in the United States. The MUTCD insures that signs use the right colors, shapes, and sizes to notify drivers and pedestrians of traffic rules and hazards.

Diamond shaped yellow road signs are specifically made this way to display the warnings. Yellow is the official color of caution or warning, and the diamond shape is also reserved only for warning signs. These yellow road signs are made to alert you of a specific hazard, such as a dead end, merging lane, or stop ahead.

Yellow road signs are highly visible, and explain to you why you should slow down and proceed with caution.

Pedestrian crossing signs are the most commonly seen yellow road signs. Deer crossing symbols, farm machinery like tractors, and fire trucks are also often found on these road caution signs, alerting drivers to these potential road hazards.

Injury Prevention Month

April is Injury Prevention Month

Slip Caution Signs

The American Academy of Orthopedic Surgeons is sponsoring April’s Injury Prevention Month. This is an opportunity to focus on safety at work, home, and on the go. OSHA reports that there are almost 3 million injuries yearly at the workplace. These injuries are from a range of hazards including improper repetitive motion or posture to serious injury such as falls.

If you look around a factory or warehouse, you will see many common caution signs warning you of danger. These caution signs alert workers of pinch and crush hazards, fall hazards, and slips and trips. These are some of the most common injuries at the workplace, and all can be prevented.

Pinch and crush caution signs look different for specific hazards. These injuries often occur during maintenance of machinery, when workers could be near pistons or stamping mechanisms. Caution signs and lockout tags alert workers in two ways: by reminding those working to power down the machines and by warning other workers that the machines are down with people near dangerous parts. Caution signs and labels on machines also alert workers of smaller moving parts that could pinch or crush while the machine is running.

Slip and fall caution signs are the most common caution sign that you would see – especially on a rainy day. Slip caution signs can be posted on walls, or made into floor signs or cones to let you know that the floor has recently been mopped or that something has spilled. A fall warning sign tells workers on platforms and rafters that a gap is present, and if not careful of their surroundings, a serious injury from the fall could occur.

There are many things that we can do this month to help prevent injuries, and a good first step would be to post and read caution signs alerting us of danger.

Common Safety and Caution Signs

If you’ve ever been in a high school chemistry lab or visited an industrial work-site then you have probably seen caution signs with special symbols informing you of safety precautions that you should take. Many of these signs display information about personal protection equipment – when to wear goggles, gloves, or hard hats. Others tell you about potentially hazardous situations that you should be cautious to avoid.

Caution signs and symbols like these are mandated to have a bright yellow background with black lettering. Their symbols serve two purposes: to give a visual description of the hazard, and to create contrast from other materials that are of a lower priority for safety.

Symbols on caution signs  include:

  • Exclamation Points
  • Biohazard Symbols
  • Radiation Symbols
  • Images of People Subjected to the Potential Hazard

There are many types of caution signs and symbols, and not all caution signs have symbols on them. There can be signs for security entrances, slippery floors, and much more.
