Facts Concerning Indoor Moulds And Their Health EffectsWe have heard or seen on advertisements phrases like toxic mould or black mould! These phrases create fear, panic and confusion. People have spent thousands of dollars in mould remediation or disposed off household items including clothes because of mould contamination. Are these decisions always based on facts or fear? It is a difficult question to answer. The objective of this article is to provide some basic facts about mould and the associated health effects to help those concerned with mould make cost-effective decisions. Three Things You Should Know About Mould. * Mould growth is a fact of life for almost all industrial and indoor environments. However, mould growth can be controlled by providing adequate ventilation and maintaining indoor humidity levels between 30-60%. When excessive moisture or water accumulates indoors, mould growth will often occur, particularly if the moisture problem remains unnoticed or un-addressed for more than 48 hours. The key to mould control is timely maintenance and prompt repairs. * Not all moulds are harmful but to be safe it is better to treat all moulds as potentially harmful. The colour of the mould does not determine whether it is harmful or not. Therefore black mould is not necessarily bad mould. Mould related health effects depend on: * types of mould present, * amount of mould one is exposed to and for how long, * individual health status or sensitivity. Children, elderly and sick people are more vulnerable to mould. * It is difficult to eliminate all mould spores in the indoor environment. However, the levels can be minimised by controlling growth. Monitor mould growth by looking for water stains or discoloration on the ceiling, walls, baseboards, floors, and window sills. Why Be Concerned About Indoor Mould and Bacteria Growth? *Health Risk. * Legal Issues. * Material Damage and Impairment of Processes. * Mould Contamination Can Affect Businesses. What Should You Do When You Find Mould? If you are an indoor mould consultant * Discuss the problem with your client and reassure them, * Have the dominant moulds identified preferably to species level. However, before sampling, prepare a sampling plan that details how and when samples would be collected, the type of samples to collect, collection requirements for each type of samples, the criteria to use to interpret results, and the benefits expected from sampling, i.e., what question(s) would be answered by the laboratory results and what actions would be taken. Share the sampling plan with the client, * Discuss the lab results with the client. If the client is concerned about their health, advise them to seek medical opinion from their family doctors, * Discuss the remediation plan (or options if any), the remediation costs and the expected results with your client. If you Are a Property Manager or Homeowner * Do not disturb the mould since this could help the mould in shedding more spores into the air. * If what you suspect to be mould covers more than 10 square feet, seek the advice of a qualified consultant immediately. If unsure of how to handle mould covering less than 10 square feet, seek professional advice. Avoid exposing yourself or others to mould. * Ask for the mould to be identified to reassure yourself or the building occupants that it is not among those that cause serious health effects. * Discuss the problem with your family doctor or if you are the property manager reassure the occupants and let them know the actions you are taking. * If you find a professional who seem to concentrate more on how the mould could or have affected you or the building occupants Article Tags: Health Effects, Mould Growth, Building Occupants Source: Free Articles from ArticlesFactory.com
