"I've used PII services for many years in root cause investigations of complex equipment, organizational issues and human error reduction, with consistently good results."

The foundation of sound industrial safety is sound human performance. Many injury-reduction programs largely ignore this fundamental principle. PII's research demonstrates that strengthening this foundation will yield more benefits than any other well-established safety program. With human performance improvement, PII is able to reduce injury rates by a factor of 5 or more. Moreover, PII's Leading Probability Risk Analysis technology is able to predict the injury risk for a given job activity and can find the most cost-effective ways to reduce the injury risk to practically zero.
Injury Event Reduction
PII has accumulated one of the largest databases of information on how workers get injured. We have performed in-depth research for clients and developed thorough understanding of how to minimize the negative impacts of the following factors:
- Monday morning effects on rule-based workers
- Tuesday effects on skill-based workers
- Black ice effects on driving injuries and trip/falls
- Tuesday dog bites
- Circadian troughs (especially among younger workers)
- After-lunch effects (especially among older workers)
- Friday afternoon rush on rule omission
- Burden-inducing short-cutting
- Inducement effects of non-compliance
- Risk and accountability effects on compliance
- Effects of just-in-time reminders
- Experience effects on decision-making and problem-solving
- Personality effects of various types of errors
- Foreign territory effects on contractors
- Dog aggression from silent endorsement and deployed loyalty
88% of injuries occur during routine work, in seemingly normal work conditions, by experienced workers.
Over a ten year span, PII has developed its unique Leading Probability Risk Analysis technology, which is able to quantify the injury and fatality risk for workers performing various tasks. This assessment accounts for many important factors that influence human performance and human error rates which could result in injury. By utilizing this exclusive technology, PII has assisted clients by:
- Analyzing all work activities at a company and determining the high-risk tasks that are insufficient in layer of protection for workers;
- Determining the most cost-effective ways to reduce injury risk;
- Identifying key factors that induce non-compliance of safety standards, correcting them in a cost-effective manner;
- Quantifying the effects of causes for injuries to workers performing seemingly routine work, and establishing cost-effective methods to solve the problem.
- Eliminating error-likely situations in the most cost-effective ways possible.
The answer is...

Tuesday is the day of the week with the highest rate of injuries in routine work.
