There is an article on ill effects of noise and about hearing protection measures. But, today I learnt that though all of us know to reduce the noise levels to below 85 dBA, it is also not advisable to reduce it below to 70 dBA as it can cause hearing problems to operators regarding instructions, warning alarms, etc.
There is also a calculator in the above link to calculate the effectiveness of hearing protection based on the results of noise survey in your shopfloor.
Though Factories Act says 90 dBA is the noise limit for 8 hour exposure, it is a good practice to subject all employees to audiometry test, if they are exposed to 85 dBA even once in a year. Though supervisors will be reluctant to send the employees to audiometry tests to avoid production loss, considering the ill effects of noise induced hearing loss (NIHL) and in extreme case may lead to loss of life if the employee is unable to hear warning alarms.

How to make safety training effective?
Today, I read to articles on makeing safety training effective. One is on presentation skills by the trainer to grab the attention of participants (Safety Daily Advisor). The other is use of safety videos. The original link is published separately in this blog.
Attention: It says that attention of the participants is short and therefore the trainer has to be careful in planning his presentations by giving introduction, a video, narration, quiz for evaluation, etc with interaction in between. This is like a typical James Bond movie which I am attracted to because of an action stunt in the beginning, titles with music, then movie.
Videos: Videos are quite effective in understanding any subject. There is a proverb that a picture speaks 100 words. We remember scenes of a movie for a long rather than the dialogues in it unless otherwise it is a punch dialogue. In the article I read, the author mentions that it is difficult to gather employees at one place to train them. Further, what I feel that general training to meet different trades of employees present in a training session will not be effective and we can't be specific to a particular trade of employees when other trades are present. To overcome this, the author rightly said that making availability of safety videos on-demand will be quite effective. If the videos are made available through intranet with monitors provided at workers' change rooms/cabins (rest places) where they take rest for sometime after lunch / tea break, those interested can see the videos of their interest. This viewing can also be done where there is no work and workers got a free time.
I got benfited a lot and my understanding of chemical safety improved when I watched CSB videos. For more details, whenever required, I went through the investigation reports of CSB. In my training sessions for fresh batches, I start with a brief introduction, followed by some principles and then show a video. There is a huge demand from participants for more videos. I give them the website addresses instead of videos as I feel that if we provide videos as such, then the CD/DVD will be lying in the cupboard without using it ever. If they themselves go to the website and watch / download videos, then, I am sure they will go through in length and make them to surf the net for more and more such videos and information.
Recently, in a training session for experienced employees, when I showed a video on impact of a gas cylinder when it valve is broken, many employees, some them on the verge of superannuation told me that for first time they understood why gas cylinder valves should be protected and why gas cylinders should be chained. Even in feedback forms, they mentioned the same. Mind you, I went for the training session to fill a gap of 15 minutes as the lunch was not ready.

A study on PPE use (not using) by workers - reasons - recommendations
There is good article on why workers do not use PPE and risk themselves to accidents. The article also elaborates on view of the safety professionals about reasons and recommendations for making the workers to use PPE.

Use of robots in automated processes - What are the safety implications?
Automation of processes is preferred by most of the organizations as it reduces human interface and improves productivity. In manufacturing / engineering industry, auto sector, etc most of the material handling jobs are automated and robots are engaged for complex jobs. This reduces lifting of weights of human beings, avoids stress / strain caused due to repetitive jobs and thus reduces health care costs.
However, it is important to understand the programming that went into sequencing of operations to be done in automated jobs and its implications particularly when the jobs are partly automated, partly manual. The job may look simple when routine sequence of operations are carried out. However, if any interruptions / change of sequence is there or breakdown occurs or power failure takes place, we need to know its impact on operations. May be we did not thought of restricting the functioning of robots or like it happens in computers when power failure occurs, there may be hanging of the computer programme. Whether such a situation creates any hazard to shopfloor operators in the vicinity is to be assessed.
Or, what are the hazards when maintenance is to be done when these automated systems are in energized condition. Whether safe positioning is incorporated when emergency stop switch is operated is to be known. Else, when someone looks into the problem during a breakdown, any of his repair job may cause the robot arm to move and hit the maintenance engineer.
Before programming the logics, a detailed WHAT IF analysis is to be done by involving concerned including design engineer, operation engineer, instrument engineer, maintenance engineer, safety engineer, etc to assess all possible hazards for all regular operations / breakdown jobs / maintenance, etc.
Still, there may be surprises depending upon the extent of questioning, imagination, thinking is put during hazard evaluation.

Why accidents continue to occur?
We read regularly in news papers that accidents continue to occur though here and there the concerned are charge sheeted. Most of the time, the families of the victims are compensated by the managements and the issue is resolved to the satisfaction of both parties. Many times, accidents are reported. It is likely that there are many accidents which are not reported and settled without notice. Though this may satisfy the aggrieved, it will not stop recurrence of accidents, if not in the same organization, as no lessons are drawn. The only lesson drawn is that it is economical to pay rather than ensure safety at workplace. This is a common sense. Why one will spend more when there are ways to reduce costs.
There will be reports for sometime in newspapers and then everybody will forget. This is true everywhere in the world. In some countries, as experts say, regulators are task masters and award huge penalties. However, the fact that accidents continue to occur in these countries shows that there is something wrong in implementation of accident prevention programme.
When there is some financial scam, more are affected and there are many stake holders in voicing there concern and try to punish the responsible. However, this is not visible in case of industrial accidents. I do not know, in how many cases, regulators stopped operations permanently after an accident. There may be suspension of operations for a while, but not as a whole. Managements can absorb losses due to suspension of operations for a while. Some can even clevery carryout maintenance works during this period which may be due after sometime and thus save time from annual shutdown.
A serious message is to be sent to managements with severe actions that can make them to realize about the importance of safety given by governments and that they may lose even their personal wealth if any accident occurs.
Otherwise, it is better for the regulators to stop issuing press notes about poor conditions in factores and be contended with the existing conditions.

Workplace accidents - where we are?
I read three articles 1) Why Safety Training is a Good Investment, 2) Safety Training Pays Off Every Minute and 3) Training Adult Learners on importance of safety training for accident reduction. According to these, in US every year there are 4.0 million non-fatal injuries, 1.0 million man-days lost, every day 15 workers die because of workplace injuries / illness. Training the persons makes them to realize, recognize, evaluate and take effective measures for control of workplace accidents and avoid its ill effects / consequences. As pointed out in the 3rd article, to succeed careerwise, people will be learning relevant new issues. However, we have to make them realize that they have to learn safety aspects also. Otherwise, there will be bloodbath at the workplace as no attention is paid for ensuring the workplace safety. Any decision for increase production without safety means somebody will be hurt in the field. The decision maker may not realize that his decision is the reason for the deaths / injuries. Like, some people say 'to give human touch', decision makers have to give 'safety touch' and assess all consequnces arising out of their consequences.
Now-a-days, in western countries, when buying or placing order on a company, organizations conduct audit including quality, environment and safety audit. Similarly, while recruiting executives, these organizations should verify the safety credentials in the previous employment. For first timers, they can assess knowledge on safety systems, applicable legislations, etc or after recruitment, they can impart safety training. It is not sufficient only to see capabilities / past experience in achieving / reaching production targets alone. Assessment is to be done for SAFE PRODUCTION. Otherwise, accidents like at Bhopal, Deep Water Horizon, etc can happen and lead to closure of the unit or selling of the assets to meet obligations.
CHOICE IS YOURS. WHICH WAY YOU WANT TO SEE YOUR ORGANIZATION.
