RT-431 Best Practices in Safety Communication and Training

Research Questions and Objective

Essential question: How can we improve the effectiveness of safety communication in construction projects to better capture attention and change behavior?

Objectives:

1- Identify best practices for communicating safety messages that are clear, engaging, and effective in influencing worker perception and behavior.

2- Examine methods for tailoring safety communication to diverse audiences, taking into account individual differences.

3- Develop strategies to effectively communicate the importance of safety practices to reduce the risk of incidents in construction projects.

The following original objective will not be prioritized but may still be covered to some extent:

4- Investigate the role of technology and AI in enhancing the delivery, engagement, and comprehension of safety messages.

Hypothesis

Effective safety communication in construction can be significantly improved by optimizing message design, delivery methods, and communication strategies to better capture workers' attention and drive behavioral change.

Assumption: Improved communication is assumed to support better safety performance, but this project will not quantitatively test safety outcome improvement.

(Expected/possible) Outcomes

Safety Communication Playbook / Roadmap with message templates, checklists, do’s/don’ts, good/bad examples, role guidance, and evaluation/closing-the-loop guidance.

Scope

Dimension	Included	Not Included + Notes

Dimension	Included	Not Included + Notes
Industry Segments	Industrial construction/Heavy construction Commercial/residential construction
Relation to CII past research	Builds on the finding that communication is a critical component of a safety program	Does not address specific questions of the IR-412 assessment
Technology awareness scope	Address rules of thumb regarding AI use based on RT member input	RT will not develop any AI tools for communication (or recommend specific tools). Optional exploratory scan; not central to the final deliverable.
Safety Topic	PPE usage Site-specific risks Emergency procedures Safety statistics and reports	Development of safety training content is out of scope
Communication characteristics	Content, format, delivery timing, frequency, visual design, actionability, relevance, messenger, and audience
Unit of analysis	Individual safety communication messages and artifacts	Not a full safety management system study
Safety Impact Objective	Retention of the safety messages	No quantitative validation of incident reduction or safety performance improvement
Validation	Expert-vetted playbook	Opinion-based validation

Methodology

Objectives: (1) Identify best practices; (2) Examine methods for tailoring safety communication; (3) Develop strategies to effectively communicated

	Step	Data/Inputs	Analysis/ Methods	Results	Obj.

	Step	Data/Inputs	Analysis/ Methods	Results	Obj.
1	Survey (breadth)	Literature Review + Survey Survey open May–July 2026; ~300 responses as of July 2nd. Data collection closes end of July.	Individuals perceptions of memorable messages Quantitative (characteristics vs. perceived outcomes), characteristics of memorable messages. Qualitative:	Industry-wide patterns in safety communication practices Ranked and weighted characteristics of memorable messages Preliminary factors identified for attention, comprehension, engagement, and compliance Sender and receiver perspectives alignment Initial set of data-driven candidates for best practices	(1)
2	Case Study for Depth	Structured case study templates (17 cases as of 7/2/2026)	Unit of Analysis: Individual safety communication case examples within real project contexts Potential Analysis: Cross-Coding Within-Case Analysis to identify causal mechanisms Cross-Case comparison between effective and less effective cases	Validation of survey findings Identify the causal mechanisms of safety communication effectiveness Refined list of success factors, barriers Compiled real-world case examples for inclusion in guidance materials	(1, 2)
3	Synthesis	Survey results Case study insights	Potential Analysis: Triangulation of qualitative and quantitative results Expert vetting (CII does not accept opinion-based validation of results. Adopt terminology that reflects the expert-ranked practices) Delphi or other method (TBD) for the prioritization of potential practices (or clarify how focus groups provide a framework do do so)	Links between factors, outcomes, and practices Prioritized list of best practices (clarify validation) Differentiate general vs. context-specific strategies for communication types	(4)
4	Develop Best Practices	Vetted best practices Strategies and case examples	TBD	Safety Communication Playbook / Roadmap including Checklists to cover the lifecycle of communication from design to delivery to evaluation Do’s and Don’ts by communication type Template library and example library as likely products.	(4)
5	AI Technology Exploration	RT member experiences Brief search of existing technologies	RT discussions	Opportunities where technology and AI can enhance safety communication effectiveness or improve design
