Survey Safety

Survey Safety

Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...

Role of Skin in Vitamin D Synthesis

Role of Skin in Vitamin D Synthesis

The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...

Skin Cancer

Skin Cancer

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Design Example: Managing Concrete Workability

Design Example: Managing Concrete Workability

This example deals with managing the workability of concrete for a raft foundation project under hot weather conditions. Workability is crucial for ensuring the concrete is easy to place, compact, and finish. In this scenario, a slump test — a common method to measure the workability of fresh concrete — initially indicated low workability. This was attributed to the rapid water loss from the concrete mix, exacerbated by the high temperatures causing the course aggregates to heat up.

Summary

Outdoor workers show poor sunscreen use despite awareness of risks. Providing sunscreen at worksites is feasible, but low participation and follow-up rates challenge future intervention studies for reducing non-melanoma skin cancer risk.

Background:

Outdoor workers (OW) face higher ultraviolet radiation (UVR) exposure, increasing non-melanoma skin cancer (NMSC) risk.
Despite awareness, OW exhibit inadequate sun-safety behaviors, particularly regarding sunscreen use.
A pilot study aimed to assess intervention elements for improving sun safety among OW.

Purpose of the Study:

Evaluate the feasibility of providing sunscreen and assessing its use among outdoor workers.
Investigate method- and intervention-related elements for a future trial.
Assess the acceptability and effectiveness of workplace sunscreen dispensers.

Main Methods:

A pilot study was conducted at a Dutch construction site with 67 outdoor workers (OW).
Sunscreen dispensers (SPF 50+) were installed, and OW completed questionnaires on sun-safety behavior pre- and post-intervention.
Stratum corneum (SC) samples were collected from OW and indoor workers (IW) to assess UV-biomarkers.

Main Results:

Sunscreen use remained low (44.4% to 35.3%) despite provision and high awareness (75%) of UVR risks.
A majority found sunscreen provision encouraging (59.3%) and dispensers easy to use (64.7%).
UV-biomarker levels were higher in sun-exposed areas, but not significantly different between OW and IW.

Conclusions:

Low sunscreen use persists among OW, even with accessible dispensers and high risk awareness.
Workplace SC sample collection is feasible for assessing UVR exposure using biomarkers.
Low participation and high loss to follow-up present significant challenges for future intervention studies.
