PPE in short supply for farm work during the COVID-19 crisis
While most Californians are staying home to slow the spread of the novel coronavirus, California farmers, farmworkers and other agricultural professionals are out in the fields and packing houses working to produce food. With increased demand for personal protective equipment, or PPE, to protect...
PPE in short supply for farm work during the COVID-19 crisis
Gloves, N95 respirators, coveralls and other gear that workers wear to protect themselves from COVID-19, pesticides, dust and other health hazards are in short supply as priority is given to health care workers during the pandemic.
To reduce the spread of COVID-19, workers may wear homemade face coverings, but for applying pesticides, they must wear respirators specified on the pesticide product label, said Whitney Brim-DeForest, UC Cooperative Extension rice advisor.
Pesticide applicators may use gear that is more protective than required by the product label and regulations. 
“Although this could change in the days ahead, half-mask and full-mask respirators are more available than disposable N95 respirators for now,” said Lisa Blecker, coordinator for the UC Pesticide Safety Education Program.
Before the pandemic, 10% of N95 respirators from 3M went to health care, but that number is now 90%, the company said in a letter to distributors. This has led to significant backorders of PPE supplies for distributors.
Carl Atwell, president of Gempler's, an online distributor of worker supplies, said that before the crisis, normal lead times for PPE was up to 10 days. He estimated disposable respirators will become available in the fall and other PPE supplies in August.
In the meantime, there is alternative PPE that agricultural professionals can use during the shortage.
Atwell suggests looking for lesser known brands of PPE as opposed to the first tier of choice: “It's sort of like searching for Purell hand sanitizer. Purell brand might be out of stock, but can you find a different disinfectant?”
On Gempler's website, the more recognizable Tyvek coverall from Dupont is sold out, however disposable protective clothing is available from other brands. Reusable chemical-resistant clothing is also available as opposed to their disposable counterparts. Supplies in high demand are reusable and disposable nitrile gloves, protective clothing, disposable respirators and certain protective eyewear, such as goggles and face shields.
For workers who will be applying pesticides, Blecker and Brim-DeForest offered some guidelines on how to meet PPE requirements as the shortage continues.
General PPE requirements: “Remember, the label is the law,” said Brim-DeForest. “PPE requirements for agriculture are not being loosened.” The UCCE advisor recommends purchasing only what you need for the season and choosing reusable PPE whenever possible. Growers who have excess supplies of PPE can coordinate with their county agricultural commissioner or UCCE advisor to help other producers in their area.
Respirators: If you can't find the respirator required on the label, Blecker said, “Use an alternative, more-protective respirator. For example, if an N95 is required, you can use a half-mask with N95 particulate filters; these can be stand-alone filters or ones that attach to an organic vapor cartridge. You could also use a different pesticide that doesn't require a respirator. Consult with your PCA (pest control adviser) for options.”
Gloves: Chemical-resistant gloves, usually 14 mil or more in thickness are required for most California pesticide applications and should be worn by mixers, handlers and applicators. If nitrile gloves are not available, viton and laminate gloves are universal chemical-resistant materials for most pesticide labels. If the glove material is specified on the label, that instruction must be followed.
“Disposable gloves less than 14 mil can be worn, but not for more than 15 minutes at a time,” Blecker said. “Farmers should also note that thinner gloves cannot be layered on top of one another.”
Coveralls: Coveralls should be worn when required by the pesticide label or when the signal word is “WARNING” or “DANGER,” or when applying by backpack or airblast. “Coveralls can be made out of high-density polyethylene fibers (Tyvek and other brands), which are disposable, or cotton, which are reusable,” Brim-DeForest said. “If reusable coveralls are worn, the employer must ensure employees are provided clean coveralls.”
Goggles/face shields: Face shields are required for mixing and loading pesticides only if it's stated on the label. “If a face shield is unavailable, a full-face respirator can be used,” Blecker said. “Goggles or protective eyewear should always be worn in California when handling pesticides, regardless of what the label says. The face shield, goggles or safety glasses must provide front, side and brow protection and meet the American National Standards Institute Z87.1 standard for impact resistance.
The UC Integrated Pest Management Program also covers these topics in their pesticide safety webinar series at http://ipm.ucanr.edu/IPMPROJECT/workshops.html.

Hmong-language pesticide safety videos now online
DPR, Fresno State and UCCE create pesticide safety videos with Hmong farmers
A series of videos describing California pesticide rules and safety in Hmong is now available to view for free online. The videos were produced by California State University, Fresno and UC Cooperative Extension in Fresno County with funding from the California Department of Pesticide Regulation.
The nine-part video series – Complying with Pesticide Laws and Regulations in California – is part of DPR's mission to reach California's farming communities. The videos cover a number of topics including using personal protective equipment, understanding pesticide product labels and application permit requirements.
The innovative educational tool blends peer-to-peer communication with traditional extension methods to include the knowledge and experience of both farmers and extension experts. Hmong farmers featured in the video helped develop scenes in which they educate other farmers, purchase and use personal protective equipment, and interact with extension staff.
“We worked with Hmong farmers who are following pesticide regulations themselves, and are now giving back to educate their peers,” said Ruth Dahlquist-Willard, UC Cooperative Extension small farm advisor, who collaborated on the video production. “Their voices and expertise helped make the scenarios more realistic and accessible to other farmers in the Southeast Asian community.”
Michael Yang, longtime UC Cooperative Extension small farms and specialty crops agricultural assistant, stars in the videos, interacting with farmers based on his extensive experience and trusted relationships in the Hmong farming community, and narrating the educational content in Hmong.
“We hope the videos broaden the reach of our local extension programming to help more farmers understand pesticide regulations and avoid fines, as well as improve their safe handling, selection and use,” said Yang.
Dahlquist-Willard and Yang plan to show the videos at UC Cooperative Extension meetings with Hmong farmers and distribute copies on flashdrives to county Agricultural Commissioner's offices in Fresno County and beyond. The videos are captioned in English.
“DPR works with all types of farmers on pesticide issues and it's critical that they use these tools safely – regardless of the language they speak,” explained DPR Director Val Dolcini. “This video project, the first of its kind to use Hmong speakers, will help foster safer use of pesticides.”
The videos can be viewed at http://bit.ly/fs-dpr-hmong-pesticide-video. The modules in the series cover:
- Introduction to California Pesticide Laws
- Checking for Crops Registered on the Label
- Pests and Application Rates on the Label
- Understanding Signal Words
- Following the Restricted Entry Interval (REI)
- Following the Pre-harvest Interval (PHI)
- Knowing Common Restrictions on the Label
- Using Personal Protective Equipment (PPE)
- Pesticide Permits and Reporting requirements
The project took 700 hours over 18 months to complete, including filming and post-production. Twelve Fresno State students were also involved in producing the videos with the Hmong farmers in Fresno County. Dahlquist-Willard and Yang provided the creative direction in partnership with the farmers involved, and Fresno State's MCJ Multimedia Production Service under Professor Candace Egan brought professional video production and editing skills to make a high-quality finished product. Fresno State student video editor Mali Lee, a fluent Hmong speaker, completed the final edits of the Hmong language material.
“This was one of the most rewarding projects I have ever worked on,” said project director Bill Erysian of Fresno State. “We brought together a unique group of agricultural specialists, students, farmers and video professionals to create a high impact, professional set of educational videos on pesticide compliance for our Hmong farmers here in California.”
DPR has comprehensive pesticide safety and outreach material available in Punjabi, Spanish and English at https://www.cdpr.ca.gov/docs/whs/worker_protection.htm.
Organic vs conventional agriculture conversation
An article was posted a couple days ago on the Scientific American blog in which the author deconstructed what she saw as common myths about organic agriculture. I thought I'd repost Christie Wilcox's article here "Mythbusting 101: Organic Farming > Conventional Agriculture" In her article,...
Making Pesticide Safety Visible
The adage "a picture is worth a thousand words" can apply to pesticide safety, too! When I was at Colorado State University in 2006, Sandra McDonald of Mountain West PEST led an effort to teach pesticide safety through the use of photos. We took over 900 photos using the fluorescent dye Glo-Germ®...
