Ergonomics are one of the biggest causes of manual labor workplace injuries.

Root causes vary from incident to incident, but there are some common themes to look out for. STEP 4: Find a solution to protect employees against the root cause in the future.Ĭonsider this 5 why analysis example that you can use as a reference for your own investigation: STEP 3: Decide the root cause once you’re finished asking “why.” STEP 2: Ask “why” five times to narrow down the root cause. What was the negative result of the workplace incident? Here are the basic steps of performing a 5 why incident investigation: Remember, your goal is to start with the broadest explanation for an incident and narrow it down to a more specific problem with each “why.” Once you have all the background information for the incident, use the 5 why incident investigation technique to figure out the root cause. Finding the root cause will then rely on the questions that you ask the injured employee. This technique is helpful for writing incident reports, especially when the root cause isn’t immediately obvious.įor example, maybe you need to do an injury investigation, but you don’t have any eyewitnesses or video footage.

Apply a fluoride gel or varnish, if necessary.

A cavity is permanent damage that a dentist has to repair with a filling.īack to top How can we help teeth win the tug of war and avoid a cavity?įluoride is a mineral that can prevent tooth decay from progressing. Over time, the enamel is weakened and destroyed, forming a cavity. Enamel can repair itself by using minerals from saliva, and fluoride from toothpaste or other sources.īut if the tooth decay process continues, more minerals are lost. Tooth decay can be stopped or reversed at this point. A white spot may appear where minerals have been lost. When a tooth is exposed to acid frequently - for example, if you eat or drink often, especially foods or drinks containing sugar and starches - the repeated cycles of acid attacks cause the enamel to continue to lose minerals.
