It is for these reasons and many more that companies must ensure employees and visitors are able to work in a safe environment. Sometimes this is not as easy, especially if the weather is bad or the building is undergoing renovation. If this is the case, you still need to provide suitable levels of security, including signs pointing out where potential problems can occur or providing the necessary safety equipment. There are certain signs that all businesses must have, and these include fire exit signs and no smoking signs that should be present somewhere within the premises. Building sites and workplaces that involve handling chemicals need a wider range of signs, including 'attention' signs and 'wear protective clothing' signs. Other signs that may be required are first aid instruction signs. These give everyone in the building information on who to contact if they require first aid. Contact details of any fully qualified first aiders in the building should appear. First aid is very important in the workplace as slips and trips are very common; if an employee hurts themselves, there must be someone available to help. Other signs a company should have at their disposal are wet floor signs. These are especially needed during the winter as weather conditions are generally poor, but having them year-round will allow you to react to the unpredictable British weather. Depending on the nature of your company and the employees and clients you have, you may require multi-lingual signs to assist people whose mother tongue may not be English. This is good practice as it helps foreign workers who may not have a full understanding of the English language, especially technical terms such as types of machinery and safety equipment. Consider what signs are needed for your company and go online to find the best deals. Having these signs will reduce the possibility of an accident in the workplace that could potentially cost you time and money.
