JAMSHEDPUR: Jharkhand Chief Minister Madhu Koda on Wednesday alleged that negligence by

Tata Motors had led to the leakage of chlorine gas from its water filter plant in Jamshedpur

"I was told that an unused chlorine cylinder had been lying in the plant for the last 10

years, and the gas leaked from that cylinder," Koda, who visited the hospital in

place. It is a clear case of negligence," Koda, who was accompanied by Deputy Chief

Alleging that the gas leak was caused due to "negligence" on the part of Tata Motors, Mahto

said quoting the official that the "gas cylinder was left abandoned in the company premises

Sarkar under section 308, 338, 337, 278 and 284 IPC. According to East Singhbhum

The FIR was lodged against the Tata Motors plant head, plant occupier, general manager

A: Out of the three cylinders that were leaking, two of them have been taken care of, there

also very less as per the technical experts.

John has been assigned to make some minor repairs in an elevated work location. Because John’s employer is conscientious about safety, he has been equipped and trained to use a fall-arrest harness with a 6-foot shock-absorbing lanyard and has been told about self-rescue techniques. 

After fastening his lanyard to a secure anchorage, John begins his tasks. Suddenly, a pigeon, disturbed by John’s work activities, flies out of a small area and startles John. He steps back suddenly and falls from the platform where he was working. The shock absorber on his lanyard extends to reduce the impact forces on his body, although it is still a hard fall, and John is left dangling in an area where he can’t reach any of the structure to be able to perform self-rescue. All he can do is yell for help and wait while the harness binds painfully around his thighs.

The industrial facility that employs John does not have a trained high angle or confined space rescue team. The management of the facility had previously decided that the cost of equipping, training and maintaining an in-house team was prohibitive and unnecessary since they had a good safety record in the workplace. The plant has a standing contract for a confined space rescue standby team during turnarounds but they are not available for response in the plant except during turnarounds.

Other workers hear John’s cries for help and decide to call 911 for assistance from the local fire department. The fire department has a big, shiny rescue truck but they are only trained and equipped for vehicle crash extrication, not high angle or confined space rescue..

The fire department responds and arrives at the site within 10-minutes of the call to 911. They quickly establish verbal contact with John to assess his condition. John tells the firefighters that he is not hurt but he can’t get back to safety without help. The firefighters determine that John is beyond the reach of the ladders they carry on their truck, he cannot be reached by crane or manlift and that a rope rescue will be necessary. They call for mutual aid from a nearby fire department with high angle rescue capabilities but it will be a 25-minute response before they arrive.

It has been 20-minutes since John has fallen and been saved by his fall-arrest system. Suddenly, John stops communicating with the firefighters and hangs limply in his harness. The mutual aid rescue team is still 20-minutes away.

When the mutual aid rescue team arrives, they quickly set up a raising system to be able to release John’s lanyard from its anchor point and then lower him to the ground. John has no vital signs and CPR is started during the trip to the hospital. Unfortunately, the hospital personnel are unable to restore John’s heartbeat and he is pronounced dead.

What Happened?

29 CFR 1910.66 Powered Platforms for Building Maintenance, Section (e)₁, Care and Use says when vertical lifelines are used, each employee shall be provided with a separate lifeline and the employer shall provide for the prompt rescue of employees in the event of a fall or shall assure the self?rescue capability of employees.

John’s employers had equipped John with a fall-arrest system and trained him in self-rescue as required by OSHA. He was uninjured by his fall but he died before he could be rescued.

Motionless or unconscious suspension in strap harnesses for even a very short time, sets up a blood venous pooling effect which becomes dangerous if rescue methods do not address this effect. Oxygen flow into the respiratory tract plus slight elevation of the legs is vitally important for the rescue of fallen workers. Speedy rescue techniques are vital.

Workers in pre-fall training should be told to keep body parts moving frequently in a post-fall wait for rescue; The term "Prompt rescue availability" means "immediate prompt relief of suspension"; Rescuers need special training for understanding suspended worker physiology

Harness Testing

At the request of OSHA, the United States Air Force’s Aeronautical Equipment Laboratory and the Aeromedical Laboratory at Wright-Patterson Air Force Base conducted a research program aimed at demonstrating the relative effectiveness of various types of fall protection harnesses.₂

The objectives of the test program were:

• To determine the post-fall suspension capabilities of three types of harnesses; the body belt, chest harness and full-body harness 
• To assess the physiological effects of prolonged motionless suspension. Motionless suspension was selected as the most crucial test to simulate the state of an individual who might be unconscious or injured prior to or as a result of a fall.

The test subject sample consisted of 13 volunteers who passed an extensive medical screening before the tests. The subjects were gently raised off the floor while wearing the test harness until their feet could not touch the floor for support. No corrective movements or strap adjustments were permitted once the subject was suspended. The subjects were suspended until their subjective tolerance was reached or until symptoms of hypotension (low blood pressure) or syncope (fainting) developed, which warranted a medical decision to terminate the test.

The measurements taken included an electrocardiogram, blood pressure, respiratory rate, test duration and subjective comments. Each harness was fitted snugly to the subject in accordance with the manufacturer’s instructions, but not to the point where the range of extremity motion or torso movement were restricted.
