Summary
Contractor safety prequalification using safety management systems (SMS) effectively predicts fewer construction injuries. Implementing robust SMS is crucial for reducing recordable and DART cases, enhancing worker safety.
Area of Science:
- Occupational Health and Safety
- Construction Management
- Risk Assessment
Background:
- Contractor safety prequalification methods often lack validation in predicting construction worker injuries.
- Existing assessments focus on safety management systems (SMS) and safety programs, but their predictive power is uncertain.
Purpose of the Study:
- To evaluate the effectiveness of contractor prequalification methods in predicting construction worker injuries.
- To determine the association between leading safety indicators and lagging injury outcomes.
Main Methods:
- Assessed leading indicators from 2198 construction contractors, including SMS, safety programs, special elements (drug testing, return to work), and OSHA citations.
- Compared these indicators to lagging indicators: recordable injury case rates (RC) and days away, restricted, or transferred (DART) injury rates.
Main Results:
- Increased SMS scores correlated with significantly lower injury rates (reduced odds and rates for both RC and DART).
- Safety programs showed inconsistent associations with injury outcomes.
- Drug and alcohol programs were linked to lower injury rates, while return-to-work programs showed no consistent association.
- More OSHA citations were associated with lower injury rates in companies with existing injuries.
Conclusions:
- Results support the use of safety management systems (SMS) in contractor prequalification.
- Emphasizes the importance of robust SMS for mitigating construction worker injuries.

Understanding the working function of different types of controllers can be illustrated with practical analogies, such as adjusting a stereo's volume equalizer. Cranking up the bass involves a phase-lead controller, which functions as a high-pass filter, while increasing the treble uses a phase-lag controller, which acts as a low-pass filter. PD controllers, similar to high-pass filters, enhance the system's response to high-frequency components. PI controllers, akin to low-pass...

01:59Lagging Strand Synthesis
61.3K
During replication, the complementary strands in double-stranded DNA are synthesized at different rates. Replication first begins on the leading strand. Replication starts later, occurs more slowly, and proceeds discontinuously on the lagging strand.
There are several major differences between synthesis of the leading strand and synthesis of the lagging strand. 1) Leading strand synthesis happens in the direction of replication fork opening, whereas lagging strand synthesis happens in the...

Certain organic substances change color in dilute solution when the hydronium ion concentration reaches a particular value. For example, phenolphthalein is a colorless substance in any aqueous solution with a hydronium ion concentration greater than 5.0 × 10−9 M (pH < 8.3). In more basic solutions where the hydronium ion concentration is less than 5.0 × 10−9 M (pH > 8.3), it is red or pink. Substances such as phenolphthalein, which can be used to determine the pH of a solution, are...

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...

02:01pre-mRNA Processing
57.4K
In eukaryotic cells, transcripts made by RNA polymerase are modified and processed before exiting the nucleus. Unprocessed RNA is called precursor mRNA or pre-mRNA to distinguish it from mature mRNA.
Once about 20-40 ribonucleotides have been joined together by RNA polymerase, a group of enzymes adds a “cap” to the 5’ end of the growing transcript. In this process, a 5’ phosphate is replaced by modified guanosine that has a methyl group attached to it (7-Methyl...
