Construction First Aid Kits

POSTED ON:

2/4/26

The construction industry has one of the highest injury and fatality rates of any industry. This is one of the reasons that construction sites are legally required to have a well-stocked first aid kit on hand. However, the standards can be vague and don’t always give specific guidance on what should be in the kit. Below, we’ve broken down both the standards governing these kits, and the meaning behind the classification and type, to help provide some clarity on an issue that every construction company deals with.

Standards: OSHA standard 1910.151(b) states that each jobsite must have at least one person trained to render first aid and that “Adequate first aid supplies shall be readily available”. However, it doesn’t have any further details on the contents of the kit. This is where the ANSI Z308.1-2015 standard is useful. This standard clarifies what a well-stocked first-aid kit contains. Some of these items include wound dressings/trauma pads and eye protection/eyewash. Any first aid kit you are considering buying should be labeled as “ANSI approved”, which means its contents meet the ANSI standard.

Class: There are two classes of first aid kits, and they are aptly named “Class A” and “Class B”.

Class A first aid kits have all the basic first aid tools that you need to treat simple workplace injuries. These are the kits you’d see in office environments.
Class B kits have almost double the quantity of some of the items in Class A kits. They also have specialized items like splints and tourniquets, to treat more serious injuries. Because of this ability to handle serious injuries, Class B kits are what you need on your job sites.

Type: Aside from just the class, you also need to determine the proper type. These types are how you determine which kit will be good for the environment you are working in. There are four types.

Type I kits are made for indoor use and are not portable. This makes them ideal for mounting inside an office.
Type II kits are also designed for indoor use, but they are portable. This makes them useful for transferring between job trailers.
Type III kits are portable and have a weather-resistant seal, making it possible for them to be used in outdoor environments. However, they aren’t designed to withstand the elements of the weather all the time. This makes them ideal for any sheltered work taking place outdoors.
Type IV kits are designed for outdoor use in tough conditions. They are completely weather resistant, durable, and portable. This makes them the ideal kit for your toughest jobsites.

There is one final note when it comes to first aid kits. Many come with over-the-counter medicines included in the kit. It is important to keep an eye on the expiration date of these medications, as you do not want an employee to get sick after taking expired medication. Beyond that, if you are stocking the proper class and type of first aid kit for all your jobsites, you should be in compliance with the OSHA standards.

OSHA Clarifies Recordkeeping Rules for Injuries Involving Personal Lithium-Ion Batteries

On January 20, 2026, the U.S. Occupational Safety and Health Administration (OSHA) issued a formal interpretation addressing whether injuries caused by personal rechargeable lithium-ion batteries brought into the workplace must be recorded on the OSHA 300 Log. There are several key takeaways listed below:

Toolbox Talks: A Simple Way to Strengthen Safety on Construction Jobsites

Around 90% of companies in the construction industry employ 20 or fewer employees. This can make it very difficult to ensure that employees are receiving the proper safety training, since resources like time and money are often limited. Those tasked with safety compliance usually have other responsibilities, making it hard for them to dedicate the necessary time to safety. However, one easy step that can be taken is the implementation of toolbox talks

Portable Heater Safety

As the calendar flips to a new year, some of the coldest weather of the season has become entrenched throughout much of the country. There are many ways to try to mitigate the effects of the cold, and one of the most common ones is the use of portable heaters. Portable heaters can help keep employees warm and allow work to continue in areas where it might otherwise be too cold to work. However, they are not without risk. There were approximately 53,636 thermal burn injuries attributed to portable heaters from 2003 to 2013, according to the National Library of Medicine. It is important to know how to safely operate portable heaters as their usage rate peaks over the coming months.

Cold Stress

The upcoming holidays don’t just mark the end of this year and the beginning of a new one. They also signal the beginning of very cold weather for much of the country. This is important because from 2003 to 2019, cold exposure caused 31 deaths and 2,770 serious injuries to workers across the U.S. Thus, threats relating to cold stress should be taken very seriously.

Top 4 Construction Site Hazards

The construction industry is inherently risky, but OSHA has identified four hazards that consistently account for over 60% of all fatalities in the industry. These four hazards are falls, struck-by accidents, electrocution, and caught-in/between accidents. They are routinely referred to as the “fatal four”. It’s important to both understand these hazards, and be aware of ways to mitigate them, in order to keep people safe on the jobsite.

Preventing Construction Site Theft

Construction companies are more likely to experience theft than any other type of loss. According to the Insurance Journal, annual equipment theft alone costs the construction industry an estimated $1 billion—and that figure doesn’t even account for stolen raw materials or the productivity lost in the aftermath. Beyond the immediate financial impact, theft can lead to higher insurance premiums, costly project delays, and significant replacement expenses. That’s why preventing theft should be a top priority for every construction company.

Heat Stress Awareness – Early Warning Signs and How to React

As the hot summer months of June, July, and August approach, heat awareness becomes critically important. From 1992 to 2022, a total of 986 employees across all industries died from heat exposure. Of those 986 employees, 34% worked in the construction industry, according to the EPA. Furthermore, the first couple of hot weeks of the summer are especially important, as 50% to 70% of heat-related fatalities occur in the first few days of someone working in hot temperatures. Thus, it is important for those in the construction industry to be aware of the risks from working in the heat.

Construction Case Study

Trench Worker Buried Leads to Contractor LitigationIn 2019, a construction worker was buried under several tons of soil when a trench collapsed at a residential job site in Iowa. The trench was estimated to be 10 to 11 feet deep and lacked the protective systems required by OSHA, such as a trench box or appropriate shoring. The absence of this essential safety equipment resulted in significant physical injuries and lasting psychological trauma, including post-traumatic stress, anxiety, and depression.
