Memo: New Heat Safety Plan for Outdoor Crews
To: All Field Crews and Crew Leaders From: Dana Ruiz, Safety Coordinator, Brightway Landscaping Date: May 15 Subject: New Heat Safety Plan starts June 1
(1) Last July, two members of our East Side crew became sick while installing a stone patio on a 96-degree afternoon. One recovered after resting in the truck's air conditioning. The other collapsed, was taken to the hospital by ambulance and missed three weeks of work. Both had been drinking soda instead of water, and neither had taken a break since lunch. We never want to see that happen again. Starting June 1, every Brightway crew will follow the Heat Safety Plan described below.
(2) Water. Every truck will carry a 10-gallon cooler of cold water and a supply of paper cups. Crew leaders will refill coolers at the shop each morning and at the noon stop. Drink about one cup of water every 15 to 20 minutes, even if you do not feel thirsty. By the time you feel thirsty, your body is already losing more water than it is taking in. Energy drinks and soda do not count toward your water.
(3) Rest and shade. Each crew leader will check the heat index on the weather app at 7:00 a.m. and again at noon. The heat index combines temperature and humidity to show how hot it actually feels. When the heat index reaches 90°F, the crew will take a 10-minute break in the shade every hour. When it reaches 100°F, breaks increase to 15 minutes every hour, and the heaviest jobs, such as hauling stone, laying sod and mowing steep slopes, must be scheduled before 11:00 a.m. Every truck now carries a pop-up canopy for job sites without natural shade. All rest breaks are paid.
(4) New and returning workers. A worker's body needs time to adjust to working in the heat. During this period, which usually lasts one to two weeks, the body learns to sweat sooner and to cool itself more efficiently. For this reason, new employees and anyone returning from a week or more away will work no more than half of a normal day in the heat during their first two days. They will build up to a full schedule by the end of their first week. Most serious heat illnesses happen in a worker's first few days on the job.
(5) The buddy system. Heat illness can affect a person's thinking, so workers often do not notice their own symptoms. Each morning, crew leaders will pair every worker with a buddy. Buddies check on each other at every break and watch for warning signs.
(6) Know the signs. Heat exhaustion causes heavy sweating, headache, dizziness, weakness and nausea. A worker with these signs should stop working, move to the shade or an air-conditioned truck, drink water and be watched closely. Heat stroke is a medical emergency. Its signs include confusion, slurred speech, fainting and hot skin. If you see any sign of heat stroke, call 911 immediately, then cool the worker with cold water and wet towels while you wait for help.
(7) Speaking up. Crew leaders have the authority to suspend work when conditions become unsafe, and no customer deadline is more important than a worker's health. No one will be disciplined for taking a break, asking for water or reporting symptoms in a coworker. In the past, some of you have told us you felt pressure to "push through" the heat to finish a job on time. Under this plan, pushing through is not the goal. Finishing the season healthy is.
(8) Crew leaders will review the plan with their crews during a five-minute "heat huddle" every morning in June. If you have questions, call me at the shop at extension 14.
Which statement best summarizes the main idea of the memo?
Pista
A main idea covers the whole memo. Check which choice fits paragraphs 2 through 7, not just one of them.
Solución paso a paso
Paragraph 1 explains why the memo was written: two workers became sick in the heat, and "Starting June 1, every Brightway crew will follow the Heat Safety Plan described below." Each later paragraph describes one part of that plan: water (paragraph 2), rest and shade (paragraph 3), a slower start for new workers (paragraph 4), buddies (paragraph 5), warning signs (paragraph 6) and permission to speak up (paragraph 7). All of these parts share one purpose: keeping outdoor workers safe from heat illness.
Choice B is a single detail from paragraph 3. Choice C goes too far: the memo says crews take breaks when the heat index reaches 90°F, not that work stops. Choice D misreads paragraph 1. Soda is mentioned as a mistake the two workers made, and the memo never talks about punishing anyone; in fact, paragraph 7 says no one will be disciplined for taking a break.
The best summary is A: Brightway is starting a plan with rules about water, rest, scheduling and teamwork to protect outdoor crews from heat illness.
Tip: Use the umbrella test. A main idea is an umbrella that every paragraph fits under. If a choice covers only one paragraph, it is a detail.
