Working with corrosive substances can be a particularly tricky business, especially due to the fact that they have the ability to attack and destroy exposed body tissues. This damage can begin as soon as an individual comes into contact with the chemical in question, which means that every possible precaution should be taken in order to ensure that this does not occur. That's why corrosive warning labels are so important. Below are reasons why corrosive substances are hazardous and what corrosive warning signs can help communicate this danger. 

Areas That can be Damaged by Corrosive Substances Include: 

  • Skin - Corrosives have the ability to cause severe irritation to the skin, and worse, can even cause blisters and burns. In the most serious cases, this can also lead to death.
  • Eyes - The severity of eye injuries can range from severe irritation to permanent blindness, depending on the strength of the chemical, and how it comes into contact with the eyes.
  • Internal Organs - Corrosives are also highly dangerous when inhaled or swallowed, and can cause serious illnesses as a result. In cases where the particles have been inhaled, this impacts the lining of the nose, windpipe and lungs. Swallowing these substances can cause damage to your mouth, throat and digestive tract.

This can Also Impact Equipment and Installations:

Corrosives also have the ability to corrode metals, plastics and wood, which can lead to a variety of further issues:

  • Damage to work equipment, components, materials and more.
  • The production of hydrogen gas on contact, which can lead to an explosion if there is an ignition source.
  • Contamination of fluids in pipes/vessels.

In order to prevent these issues, a number of precautions should be taken, which is why we supply several corrosive warning signs. Including:

Wherever measurements are required, calibration is a vitally important (and slightly time-consuming) stage of that process. It is also important to make your staff aware that they do not need to calibrate certain items via Calibration Not Required labels.

Quite simply, calibration is when an instrument is compared to a known standard to check its accuracy. Regular calibration allows businesses to have confidence in the results they monitor and record, and to know with certainty that the results they are producing are correct. For example, when measuring temperature and humidity, calibration is required because the readings and their accuracy can start to drift if not regularly calibrated. 

In an environment where calibration is required for a wide range of equipment, 'Calibration Not Required' labels become a necessity. Not only do they ensure that your staff areaware of what they should do, they also save vast amounts of time. Members of staff will not accidentally waste their time calibrating equipment which does not need it.

Fires are a health and safety issue which impact each and every one of us, be it at home, at work or in public spaces. In order to ensure that the conditions for preventing fires from spreading are in place, it is essential to provide and maintain reliable equipment, particularly in areas which present particulalrly high risks in the event of a fire.

Although having appropriate fire extinguishers in designated areas is a great start, it is not enough to simply have these in place, and later forget about them unless they are needed. Fire extinguishers require regular inspection and servicing by professionals, in order to ensure that they are in proper working order, and have not been compromised in any way. If unfortunate circumstances did cause a fire to occur, you would want to confident in the knowledge that your extinguisher is ready to use, with no issues preventing it from serving its indented purpose.

Here are a few essential steps that need to be followed whilst performing fire extinguisher maintenance:

Perform a Visual Inspection of the Extinguisher 

The person responsible for fire safety should carry out visual checks on a monthly basis at the very least, with more frequent checks taking place where circumstances require. Your visual check should consist of the following:

  • Ensure that the extinguisher is located in the correct area, and is visible to those who may need to use it.
  • Check that the instructions are also clear to see, and unobstructed.
  • Assess the parts to ensure that it has not been damaged or operated.
  • Read the pressure gauge/indicator to check it is within safe operational limits.

Arrange Corrective Action

If the extinguisher has been tampered with, or the responsible party suspects that it is not in working order, this issue should be addressed immediately, with corrective action being arranged as soon as possible. 

Oversee Professional Servicing

Professional fire safety experts should always be used to perform detailed inspections on the extinguishers. The frequency of these inspections will depend on the type of extinguisher in question. 

Accurately Record Maintenance

As is the case with any health and safety procedure, it is essential to ensure that the processes of maintaining your fire extinguisher is also accurately recorded. To do this you will need to use fire extinguisher maintenance labels. Here's a closer look at the recording system we provide here at Label Source as an example:

(fire extinguisher maintenance labels, supplied in packs of 50)

This label should be used to record the details of the inspection, including the date, name of the inspector and weight of the extinguisher.
