t seems appropriate that I 
use this article to update 
our members on heat illness 
prevention. First, remember that 
the OSHA Heat Illness Prevention 
Standard is still pending at OSHA. 
As I hope you will recall, virtual 
public hearings were held on this proposed standard 
in July 2025. As a result of this, the record was 
opened for anyone to submit written comments until 
October 30, 2025. OSHA established a National 
Emphasis Program (NEP) for Heat Illness Prevention, 
which was set to, and did, expire on April 8, 2026. 
However, on April 10, 2026, OSHA established a 
new NEP for five more years. In doing so, OSHA has 
reminded employers and employees that it takes heat 
illness, and the injuries it can cause, very seriously. 
In the new NEP, OSHA has updated target 
industries using current data from the Bureau of 
Labor Statistics and OSHA. These industries have 
been identified as residential building construction; 
non-residential building construction; foundation, 
structure and building exterior contractors; building 
finishing contractors; and other specialty trade 
contractors as target industries for heat illness 
prevention enforcement. I believe that this covers 
just about any employer in any area of construction. 
OSHA has also provided information on points that an 
OSHA compliance officer (CSHO) is to consider when 
evaluating an employer’s Heat Illness Prevention 
Program. These include:
1.	 Is there a Heat Illness Prevention Program 
in place that is effectively communicated to 
employees?
2.	 How does the employer monitor the ambient 
temperature and the levels of work exertion at the 
worksite? With this, OSHA is emphasizing that

EFFECTIVE DATE: April 10, 2026 
ABSTRACT 
Purpose: 
This Instruction describes policies and procedures for the continued 
implementation of a National Emphasis Program (NEP) to protect 
employees from heat-related hazards and resulting injuries and illnesses 
in outdoor and indoor workplaces in general industry, construction, 
maritime, and agriculture.  This NEP sets forth a targeted enforcement 
component and reiterates compliance assistance and outreach efforts.  
This approach is intended to encourage early interventions by employers 
to prevent illnesses and deaths among workers during high heat 
conditions, such as working outdoors in a local area experiencing a heat 
wave, as announced by the National Weather Service.   
Scope: 
This Instruction applies OSHA-wide.
