Ahead of potential shortages for supplies and equipment needed for hospitals to treat Covid-19 patients, a group of public companies are looking at ways to help.

Manufacturers Honeywell International (ticker: HON) and 3M (MMM) are stepping up production of N95 industrial face masks—which Vice President Mike Pence says can now be sold directly to hospitals in need.

LVMH Moet Hennessy Louis Vuitton (LVMH.ITALY) is making hydroalcoholic gel for hand sanitizer in facilities used for its perfumes and cosmetics. Car companies could shift gears toward producing ventilators.

“American manufacturers are repurposing factories,” President Donald Trump said Wednesday in a press briefing. “One major manufacturer has already doubled capacity, and we’ve asked construction companies to donate unused masks.”

Honeywell spokesman Eric Krantz confirmed the company has increased production at multiple facilities globally to address growing demand.

“We are well-positioned to further help the U.S. government address COVID-19 response efforts,” he said, adding that Honeywell is “rapidly moving to add capacity in the U.S. for N95 face masks.”

Though 3M representatives did not return Barron’s requests for comment, a spokeswoman told The Washington Post the company has increased production of such masks at its U.S., China, Europe, and Latin American facilities, and is dedicating more of its output to health care rather than industrial customers.

“Those companies have now greatly increased by the tens of millions their production of so-called N95 masks that will give our health care workers the protection that they need to administer to those who are dealing with the symptoms or the disease of coronavirus,” Pence said in a press briefing Thursday, referring to 3M and Honeywell.

General Electric (GE) said its GE Healthcare subsidiary is committing more production lines to ventilators and adding shifts so lines can be active 24 hours a day.

Ford Motor (F) and General Motors (GM) have all commented publicly on the possibility of using their facilities to produce ventilators—a key piece of equipment in treating more serious Covid-19 cases.

“As America’s largest producer of vehicles and top employer of autoworkers, Ford stands ready to help the administration in any way we can, including the possibility of producing ventilators and other equipment,” Ford spokeswoman Rachel McCleery told Barron’s.

McCleery confirmed Ford has had preliminary discussions with the U.S. and U.K. governments and are looking into the feasibility of producing ventilators. “It’s vital that we all pull together to help the country weather this crisis and come out the other side stronger than ever,” she added.

A General Motors representative told Barron’s that, though early, it is evaluating such options, adding that the company is exploring how it can help.

Tesla (TSLA) CEO Elon Musk said in a Twitter post that his company could produce ventilators—if there were shortages.

“Tesla makes cars with sophisticated hvac systems,” Musk wrote on Twitter. “SpaceX makes spacecraft with life support systems. Ventilators are not difficult, but cannot be produced instantly. Which hospitals have these shortages you speak of right now?”

New York Mayor Bill de Blasio said his city would buy such equipment, adding the country is facing a “drastic shortage and we need ventilators ASAP—we will need thousands in this city over the next few weeks.”

Musk responded, “Sounds good, we will connect with your team to understand potential needs.”
