Reopening business after Coronavirus

Employers and employees around the world are anxious to get back to work as soon as possible. A picture of how that will unfold is starting to emerge — and it’s far from straightforward.

Businesses have long relied on a five-tier inverted pyramid called the “hierarchy of controls” to reduce workplace risks to employees, ranging from chemical exposure to physical injury. This framework will also be the basis for companies’ plans to get back to work, occupational safety experts say.

Companies in China have already begun following the hierarchy to restart production. But the process has been expensive and slow, as it is likely to be in the United States. That’s because many of the standard tools for workplace safety are ineffective against a risk like the coronavirus.

Distributing face masks and nagging employees to wash their hands count among the more uncertain methods for ensuring employee safety, experts say. But these are largely the methods that Chinese companies have been relying on as they have restarted production — and American businesses may not have many better options.

Governments and companies face a difficult choice in coming weeks: They can either reopen business with layers of stifling and expensive hygiene controls, or return to work with fewer controls and accept the risk of second-wave infections. Either way, there’s no silver bullet against further community spread, and the global economy cannot sustain lockdown until a vaccine is developed — which could take at least another year.

Elimination

Susan Arnold, an associate professor at the University of Minnesota’s School of Public Health, said that the most effective way — the top rung of the hierarchy of controls — to keep workers safe from a health risk is to eliminate it from the workplace. This is easy if the risk is a toxic chemical or dangerous machine, but not currently possible for the virus, she said.

“When we have a vaccine that’s widely available and accessible, then we will be in the position to eliminate that hazard from the workplace,” she said. “The only other way to do that right now is to shut workplaces down.”

As Chinese businesses return to work, Beijing has sought to reduce the transmission risk by requiring employers to check employees’ health and temperature daily, with quick quarantine for anyone showing symptoms. But some covid-19 patients are asymptomatic and test kits can produce false negatives, making these checks far from foolproof.

  1. Elimiinate non-essential services;
  2. Eliminate non-essential personnel visiting the workplace by providing means for home-working;
  3. Suspended the use of fingerprint-entry keypads;
  4. Forbidden workers from sitting face-to-face while eating lunch;
  5. The number of people allowed in a bathroom simultaneously is two;

Substitution

The next most-effective method on the hierarchy of controls is to find a safer substitution.

  1. Substitute supplier with one from less infected area
  2. Substitute material with one, supplied from areas not under quarantine
That leaves the three rungs that workplace safety experts have long considered the least effective and most costly: engineering controls, administrative controls and personal protective equipment, or PPE.

Engineering controls

Engineering controls, or redesigning workspaces to physically prevent virus transmission, are the next line of defense.

  1. Mats soaked in disinfectant at entrances.
  2. “sneeze guards,” or walls of plastic or glass, to protect cashiers in  retailers.
  3. Adjusting production lines to provide more space between workers. Factories may face limits in how much they can space out assembly lines
  4. Cardboard dividers have been set up on lunchroom tables to separate diners;
  5. Improve ventilation, either through air filtration or introducing outside air.
  6. Cafeteria seats have been labeled with QR codes for workers to scan so the company has a record of who sat where and when for meals. (Foxconn Technology Group)
  7. Infrared video camera that tracks employees’ body temperatures as they walk by; (Foxconn Technology Group)

Administrative controls

Many of the measures that are easiest for businesses to adopt are administrative controls, which are safety protocols for workers to follow:

  1. Frequent handwashing.
  2. Work schedules that minimize employee crowding. Some Chinese Internet companies have returned to work in recent weeks on “AB shifts,” with two teams coming into the office on alternate days. At least consider leaving some time between shifts to minimize crowding
  3. Check temperatures daily.
  4. Bring their own towels to dry their hands after hand-washing
  5. Disinfect hands and shoes at the factory gate.
  6. Employers must submit daily reports on workers’ health statuses;
  7. Provide accomodation for essential workers in company premises;
  8. Appoint Campboss to control movement in the campuss;
  9. Workers forbidden from leaving campus without permission;
  10. Provide workers with company transportation to prevent mixing in public transport;
  11. Opening office windows three times a day for 30-minute stretches;
  12. Teams of 20 that stick together night and day to facilitate health tracking; (Foxconn Technology Group)
  13. All employees to submit a daily health report before noon;
  14. Managers should randomly select two employees morning, midday and evening for spot checking if they have washed their hands. (Huawei)

Personal Protective Equipment

The small, pointy base of the hierarchy of controls is personal protective equipment, which occupational safety experts consider the least-effective method and the safeguard of last resort. The emergence of the term “PPE” as a household phrase in recent weeks reflects how the other four rungs have proved ineffective at stemming the spread of the virus.

  1. There is growing international consensus that workers outside the health-care industry should also wear face coverings for protection, though also concern that scarce mask supplies might be diverted from hospitals if the general public scrambles for them. The Centers for Disease Control and Prevention has recommended the American public wear cloth face coverings, not medical-grade masks.
  2. In China, some manufacturers like Foxconn have begun producing their own masks to ensure a steady supply for their assembly-line workers.

Employers should consider what they can do at each of these five levels, as they prepare to reopen.

As for employees preparing to go back to work, please consider:

“Just be mentally thinking that any of my co-workers could still be potentially a source of exposure. Anything I touch could potentially be a source of exposure.”

    Excellent insight. Thanks for sharing

    I give below my views on the Dos & Don’ts on the day of restarting of the factory/ company.

    1. Before energizing any machine/ equipment, let authorized LOTO employees apply LOTO and check for any cable, pipes, hoses, etc., cut by Rodents since no canteen food was available to them.

    2. Arrange good housekeeping & 5S including segregating rusty components

    3. Inform employees to clean their machines only after ensuring the energy is isolated

    4. If required, prepare SOP on Dos & Don’ts on Corona for the employees to follow since Corona would not have been eradicated.

    5. Keep Alcohol based sanitizers away from source of ignition.

    6. Do not try to speed your jobs to make up your lost production which may deteriorate the quality of the work and lead to accidents.

    7. Refresh the employees with toolbox talk/ Pep talk on safety

    8. Machines using Coolant(water based emulsion) will be stinking and dispose them as per SOP by wearing PPE. The same case with Oil.

    9. Those using grinding machine with coolant should not start grinding immediately after starting the machine as there are chances of wheel breakage because, the coolant will be settled / collected at the bottom of the grinding wheel due to long stoppage of whee and it would be inbalanced due to weight at one side. To avoid this, before starting grinding, do inching of the grinding wheel 3 to 4 times so that the coolant collected inside the wheel will spread across and wheel and weight get balanced.

    10 .Let maintenance staff ensure correct oil level, freezing of grease, etc., in the machine spindles, gear boxes, etc.

    11. Cleaning of overhead drinking water tanks (with confined space entry Permit) and clearing taps.

      Anoop,
      Amazing points to consider. I am pretty confident, having Corona in the agenda for quite a long time now, many people may easily skip basic HSE rules, as well as rush to resume operations and oversee hidden hazards generated by stagnant work places and idle machines.
      Thanks again
