Government Guidelines for Restarting Manufacturing Industries After Lockdown

by Imaging Solution Bureau

The Union Ministry of Home Affairs (MHA) has issued guidelines for restarting manufacturing industries after the COVID lockdown. As a step towards exiting lockdown, the Ministry of Home Affairs has issued guidelines for restarting manufacturing industries after lockdown as a trial or test-run. The Ministry has directed to ensure all safety protocols are followed while keeping the production targets low.

The companies are directed to carry out a complete safety audit of the entire unit before restarting the activities. As per the guidelines, Cleaning of all pipelines, equipment, and discharge lines needs to be undertaken before resuming operations. The companies are also directed to conduct tightness tests, service tests, and vacuum tests of plants and equipment which handle combustibles or toxic substances, the leakage of which could prove disastrous, damaging, or resulting in economic loss. Trial tests must be carried out before the fullfledged operation is initiated with full capacity and manpower. The MHA has also directed the companies to ensure the arrangement of round the clock emergency crews and professional technical teams with Major Accident Hazard (MAH) installations. The detailed guidelines are as follows:

Guidelines for restarting manufacturing industries after lockdown

In an early response to COVID-19, the nationwide lockdown was ordered with effect from 25th March. As the lockdown is being gradually released in some zones, certain economic activities are being permitted as per NDMA orders No.1-29/2020-PP dated 1st May 2020 and MHA order No. 40- 3/2020-DM-I(A) dated 1st May 2020.

Due to several weeks of lockdown and the closure of industrial units during the lockdown period, it is possible that some of the operators might not have followed the established SOP. As a result, some of the manufacturing facilities, pipelines, valves, etc. may have residual chemicals, which may pose risk. The same is true for storage facilities with hazardous chemicals and flammable materials.

National Disaster Management Authority has issued 1. Guidelines on Chemical Disasters, 2007. 2. Guidelines on Management of Chemical (Terrorism) Disasters, 2009 and 3. Strengthening of Safety and Security For Transportation of POL Tankers,2010, which are relevant for chemical industries. The Manufacture, Storage, and Import of Hazardous Chemical Rules, 1989 under Environment Protection Act, 1086 provide the statutory requirements for these industries.

When Lockout/Tagout procedures are not in place, many energy sources can prove to be hazardous to operators/supervisors who are servicing or maintaining electrical, mechanical, or chemical equipment. When heavy machinery and equipment are not maintained periodically, they can become dangerous for operators/engineers.

Combustible liquids, contained gaseous substances, open wires, conveyor belts, and automated vehicles that make manufacturing facilities a high-risk environment. Improper enforcement of safety codes and improperly labeled chemicals can further pose serious health hazards.

When an unexpected event occurs, managing rapid response becomes challenging. In order to minimize the risk and to encourage a successful restart of the industrial units, the following guidelines are being issued.

State Governments shall also ensure that the off-site disaster management plan of the respective Major Accidental Hazard (MAH) units are up to date and preparedness to implement them is high. It is also advised that all the responsible officers of the district shall ensure the Industrial On-Site Disaster Management Plans are also in place and cover Standard Operating Procedures for safe re-starting of the industries during & after COVID 19 lockdown.

Generic guidelines:

  • While restarting the unit, consider the first week as the trial or test run period; ensure all safety protocols; and not try to achieve high production
  • To minimize the risk it is important that employees who work on specific equipment are sensitized and made aware of the need to identify abnormalities like strange sounds or smell, exposed wires, vibrations, leaks, smoke, abnormal wobbling, irregular grinding or other potentially hazardous signs which indicate the need for immediate maintenance or if required
  • Especially during the Covid-19 times, ensure all lockout and tag-out procedures are in place on a daily basis (not applicable for units running 24hrs).
  • Inspection of all equipment as per the safety protocols during the restart phase
  • In case the industry has any difficulty in managing crucial backward linkages that may be critical for their safe functioning, they should approach the local district administration for specific assistance. District Magistrates may be instructed to ensure that in such instances, the industrial unit may be facilitated to run their end to end operations, in the overall interests of industrial security.

For specific industrial processes:

Storage of raw material

  • Inspect the storage facilities for any signs of spills, wear and tear during the
  • Check for already opened storage vessels/containers/bags/silos for possible oxidation/chemical reaction/ rusting/ rotting
  • HAZMAT Chemicals in the storage need to be checked for chemical stability before using for any processes
  • Ensure ventilation and proper lighting before entering the storage areas
  • Sense for abnormalities like strange sounds or smell, exposed wires, leaks, and smoke
  • Check supply pipelines/valves/conveyor belts for any signs of damage/wear & tear
  • Check the storage building for any signs of distress and damage to the

Manufacturing Processes

  • Carry out a complete safety audit of the entire unit before taking up starting activities
  • Cleaning of pipelines, equipment and discharge lines: Mechanical cleaning followed by air /water flushing and chemical cleaning based on the type of the process equipment
  • Run-in of rotatory equipment under supervision
  • Boilers/ furnaces/ heat exchangers to be checked for lining and signs of wear and tear
  • Check supply pipelines/valves/conveyor belts for any residual material and wear and tear. Also, check all the pipelines/valves for obstructions/ pressure
  • Ensure all pressure, temperature gauges are functional
  • Tightness test: Many process units handle combustibles or toxic substances (or both), the leakage of which could result in disaster, damage, or economic loss. To prevent the occurrence of such incidents, it is necessary to confirm that the plant complies with the required tightness before the start-up.
  • Service test needs to be performed for all water, compressed air, and steam piping and equipment with normal operating The system is first pressurized with operating fluids and then checked for leakage. For airlines, leaks can be found using a soap solution. For water and condensate lines, the leakage can be observed visually. Leakage points found during the test are retightened. The test is deemed successful if no foam is observed from a soap solution, or if no water or condensate is observed visually.
  • Vacuum hold test: All vacuum systems must be leak tested. The air inside the system is first evacuated to attain the required vacuum. The best way is to start at one end of the section and work through to the other end, checking flanges, valves, fittings, instruments, and other equipment. Each leak is tagged, making it easy for the maintenance team and personnel of the next shift to continue with the
  • Trial testing be carried out before the full-fledged production is initiated with full human resources
  • Ensure the arrangement for round-the-clock emergency crews/ professional technical teams provided with MAH and cluster of MAH should have extended coverage of 200 km to reach transport accident spots for help

Storage of products

  • Check the storage facilities/silos for any damage or wear and tear

Guidelines for the workers

  • Ensure 24 -hour sanitization of the factory
  • Factories need to maintain a sanitization routine every two-three hours especially in the common areas that include lunch rooms and common tables which will have to be wiped clean with disinfectants after every single
  • For accommodation, sanitization needs to be performed regularly to ensure worker safety and reduce the spread of
  • Entrance health checks
  • Temperature checks of all employees to be done twice a
  • Workers showing symptoms should not report to
  • Provisions of hand sanitizers and mask to all
  • Providing gloves, masks, and hand sanitizers to be done at all factories and manufacturing units.
  • COVID 19 health and prevention of staff education
  • Education on safety steps to take from entry to exit in the factory
  • Measures to take precautions at a personal level
  • Quarantine measures for supply and storage of goods
  • Sterilise boxes and wrapping brought into factory premises
  • Isolate and sanitize finished goods as appropriate
  • Delivery of goods in shifts
  • Physical distancing measures
  • Create physical barriers to ensure the physical distance within the work floor and dining facilities
  • Provide face protection shields along with masks and
  • Working in shifts
  • Factories that work 24 hours at full production capacity should consider one hour gap between shifts, except factories/plants requiring continuous
  • Managerial and administrative staff should work one shift at 33 percent capacity as per MHA guidelines; but while deciding which particular person to be included in 33% at any given point of time, overriding priority should be given to personnel dealing with
  • Ensure no sharing of tools or workstations to the extent possible. Provide additional sets of tools if
  • Scenario plan on discovering a positive case
  • Factories have to prepare accommodation to isolate workers, if
  • HR has to help manage the whole process for the individual, all traveling employees also to undergo a mandatory14-day quarantine

Presence of skilled workers: Workers involved in dealing with hazardous material must be skilled and experienced in the field. No compromise on the deployment of such workers should be permitted when an industrial unit is opened up.
