SUPPLEMENTARY INFORMATION: 

I. Background

    On September 16, 2009, the National Institute for Occupational 
Safety and Health (NIOSH), Centers for Disease Control and Prevention 
(CDC) announced in the Federal Register plans to evaluate the 
scientific data on 1-bromopropane (1-BP) and to issue its findings on 
the potential health risks. The results of this evaluation are 
presented in the draft document, Criteria for a Recommended Standard: 
Occupational Exposure to 1-Bromopropane (1-BP). The purpose of the 
public meeting and public comment period is to obtain comments on the 
draft document. Special emphasis will be placed on the following:
     Whether the health hazard identification, risk estimation, 
and discussion of health effects of 1-BP are a reasonable reflection of 
the current understanding of the scientific literature;
     Identifying workplaces and occupations where exposure to 
1-BP may occur;
     Identifying studies on health effects associated with 
occupational exposure to 1-BP that were not identified in the draft;
     Identifying current strategies for controlling or 
preventing exposure to 1-BP (e.g., engineering controls, work 
practices, personal protective equipment);
     Identifying current exposure measurement methods and 
challenges in measuring workplace exposures to 1-BP; and
     Identifying areas for future collaborative efforts (e.g., 
research, communication, development of exposure measurement and 
control strategies).
    As part of the review of this draft criteria document, reviewers 
are asked to address the following critical questions:
    (1) Does the draft criteria document accurately identify and 
characterize the health hazards of occupational exposures to 1-BP based 
on the current understanding of the scientific literature? Please 
identify any additional relevant literature that NIOSH should consider 
when developing its recommendations. Is the risk estimation for 1-BP 
presented in the draft criteria document a reasonable reflection of the 
current understanding of the scientific literature? Please describe any 
changes in the risk estimation that NIOSH should consider and provide 
supporting scientific literature.
    (2) Are there other risk assessment methods or health endpoints 
that NIOSH should consider for estimating risks of 1-BP? Please provide 
supporting scientific literature or other evidence to support your 
recommendations.
    (3) In this draft criteria document, NIOSH proposes a recommended 
exposure limit (REL) to prevent a risk of one excess cancer in 1000 
workers exposed to 1-BP for a 45-year working lifetime. During 
development of the draft criteria document, NIOSH also considered 
setting the REL at a level to prevent 1 excess cancer in 10,000 workers 
for a 45-year working lifetime. Please comment on the excess cancer 
risk level and resulting REL for 1-BP.
    (4) Is the relationship between exposure to 1-BP and biological 
activity (toxicity) accurately presented in the draft criteria 
document?
    (5) Are the recommended strategies for controlling or preventing 
exposure to 1-BP (e.g., engineering controls, work practices, personal 
protective equipment) reasonable and technically feasible?
    (6) Are there other techniques or technologies capable of 
controlling workplace exposures to 1-BP that should be discussed in the 
draft criteria document?
    (7) Are the exposure measurement methods and the associated 
challenges in measuring workplace exposures to 1-BP adequately 
addressed in the draft criteria document?
    (8) Are there medical screening and surveillance measures, such as 
specific diagnostic tests, guidelines, and metrics, that should be 
implemented for workers expected of being exposed to 1-BP that are not 
discussed in the draft criteria document?

[[Page 7123]]

    (9) Are there biological indices or metrics that should be used to 
aid in the interpretation of biomonitoring data for 1-BP? What is the 
most appropriate biomarker that can confirm and quantify occupational 
exposures to 1-BP?
    (10) Should acute exposure recommendations, such as a short term 
exposure limit (STEL), be derived for 1-BP? If so, what data support 
the development of the STEL?
    (11) NIOSH provided Globally Harmonized System (GHS) of 
Classification and Labelling of Chemicals designations for health 
endpoints evaluated in the criteria document. Please comment on the 
utility of these classifications for hazard communication. Are these 
classifications helpful for employers?
