Achieving compliance with pool fencing legislation in New Zealand: a survey of regulatory authorities.

OBJECTIVES: To identify the status of compliance and enforcement of New Zealand's Fencing of Swimming Pools Act (FOSP Act), 10 years after its introduction, and to identify methods for improving both compliance with the act and the process of enforcement. METHODS: A postal questionnaire was sent to all 74 authorities in New Zealand in which they were asked questions about their enforcement of the FOSP Act. Semistructured telephone interviews were conducted with 12 authorities to supplement the data obtained in the postal survey. RESULTS: Based on responses to the survey, it was estimated that there are over 59,000 domestic swimming pools in New Zealand, giving rates of 46 pools/1000 dwellings and 16 pools/1000 persons. The authorities reported that 44% of pools complied with the act, and a further 4% had been granted exemptions. Nineteen per cent of pools were reported to not comply with the act, and the compliance status of a further 33% was not known, or not stated by the authority. Only 9% of authorities had procedures for locating and inspecting pools, while 28% had a programme of reinspection to ensure that pools continued to comply. Pool owner resistance was considered to be the main difficulty with enforcing the act, and nearly half of the authorities believed publicity or education was needed to overcome these barriers. Fifty two per cent of authorities had publicized the act during the 12 months preceding the survey. CONCLUSIONS: Due to ambiguities within the legislation, and differing levels of commitment by authorities to locate pools and monitor compliance, compliance with the FOSP Act is not consistent nationally. If the act were less ambiguous, there would be greater consistency and more enforcement.

An engineering approach to controlling indoor air quality.

Evidence is accumulating that indicates air quality problems in residential and commercial buildings are nearly always associated with inadequacies in building design and methods of operation. Thus, the very systems depended on to control the indoor environment can become indirect sources of contamination if diligence is not exercised at each stage of a building's life: a) planning and design, b) construction and commissioning, c) operation, and d) demolition or renovation. In this paper, an engineering perspective is presented in which the existing building stock is characterized in terms of its environmental performance. Preliminary data indicate that 20 to 30% of the existing buildings have sufficient problems to manifest as sick-building syndrome or building-related illness, while another 10 to 20% may have undetected problems. Thus, only about 50 to 70% of the existing buildings qualify as healthy buildings. Two methods and three mechanisms of control are described to achieve "acceptable" indoor air quality: source control and exposure control. If sources cannot be removed, some level of occupant exposure will result. To control exposures with acceptable values, the primary sensory receptors of the occupants (i.e., thermal, ocular, auditory, and olfactory) cannot be excessively stimulated. The three exposure control mechanisms are conduction, radiation, and convection. To achieve acceptable occupant responses, it is often practical to integrate the mechanisms of radiation and convection in heating, ventilating, and air conditioning systems that are designed to provide acceptable thermal, acoustic, and air quality conditions within occupied spaces.(ABSTRACT TRUNCATED AT 250 WORDS)

Sick-building syndrome.

The sick-building syndrome (SBS) is defined as the occurrence of an excessive number of subjective complaints by the occupants of a building. These complaints include headache, irritation of the eyes, nose, and throat, lethargy, inability to concentrate, objectionable odors, and less frequently, nausea, dizziness, chest tightness, etc. These complaints will always be reported by a fraction of the occupants of any building if a questionnaire is administered that asks the respondent to recall any subjective symptoms they remember having had in the last 2 weeks or or over some period of time. It is often considered that SBS symptom reports have a minimum prevalence of about 15 to 20% for a 2-week recall period. SBS symptoms reported by 30% or more of occupants are indicative of conditions in the building environment that warrant attention. It is not often that a clear, single cause is responsible for the excess symptom reports. The following factors, often in combinations, are seen to contribute to SBS: outdoor air supply that is inadequate, ventilation distribution or effectiveness that is inadequate, the presence of temporary or long-term sources of contaminants such as tobacco smoke, adhesives, composite materials such as chipboard, and the growth of microorganisms in the HVAC equipment or in carpets or other furnishings. Depending on which causes contribute, the condition may be intermittent or even temporary. Psychosocial factors such as labor-management relations and satisfaction or dissatisfaction with other factors in the work environment can have a profound influence on the level of response of the occupants to their environment. Although hard data are difficult to collect, it is likely that productivity in the office environment is sensitive to conditions causing SBS.

Exposure to lead and length of time needed to make homes lead-safe for young children.

OBJECTIVES: We determined the length of time needed to make homes lead-safe in a population of children aged 0 to 6 years with blood lead levels (BLLs) of 20 micrograms per deciliter (mug/dL) or greater. Reducing this time would reduce children's exposure to lead. METHODS: Data came from the Wisconsin Childhood Lead Poisoning Prevention Program's comprehensive blood lead surveillance system. Analysis was restricted to children whose first BLL test value during 1996-1999 was between 20 and 40 mug/dL and for whom housing intervention data were available (n=382). RESULTS: The median length of time required to make a home lead-safe was 465 days. Only 18% of children lived in homes that were made lead-safe within 6 months; 45% lived in homes requiring more than 18 months to be lead-safe. CONCLUSIONS: Efforts are needed to reduce the time it takes to make a home lead-safe. Although abatement orders always include time limits, improved compliance with the orders must be enforced. Greater emphasis should be placed on securing lead-safe or lead-free housing for families, thus reducing lead exposure.

America's affordable housing crisis: a contract unfulfilled.

For many poor Americans, having a decent home and suitable living environment remains a dream. This lack of adequate housing is not only a burden for many of the poor, but it is harmful to the larger society as well, because of the adverse effects of inadequate housing on public health. Not only is the failure to provide adequate housing shortsighted from a policy perspective, but it is also a failure to live up to societal obligations. There is a societal obligation to meet the housing needs of everyone, including the most disadvantaged. Housing assistance must become a federally-funded entitlement.

The built environment and its relationship to the public's health: the legal framework.

The built environment significantly affects the public's health. This was most obvious when infectious disease was the primary public health threat during the industrial revolution; unsanitary conditions and overcrowded urban areas facilitated the spread of infection. However, even today in the age of chronic diseases there remains an important connection between population health and the built environment. Physical spaces can expose people to toxins or pollutants and influence lifestyles that contribute to diabetes, coronary vascular disease, and asthma. Public health advocates can help shape the design of cities and suburbs in ways that improve public health, but to do so effectively they need to understand the legal framework. This article reviews the connection between public health and the built environment and then describes the legal pathways for improving the design of our built environment.

Urban traffic noise and self-reported health.

This paper analyzed urban traffic noise effects on health at two different levels: intense noise and moderate noise. 42 residents of the area responded to questions on perceived noise and psychological and behavior disturbance before and after acoustic insulation was constructed. Analysis of self-reports indicated that perceived noise was associated with lower health. Also these perceived effects on health did not decrease after the acoustic isolation work was finished.

Experimental studies of subjective response to road traffic-induced building vibration.

The road traffic-induced building vibration was recorded continuously for 24 hr in three orthogonal axes outside and inside the building. Several alternative objective methods of quantifying the severity of exposures to whole-body road traffic-induced building vibration are used. The relationship between the results of all objective evaluation methods of vibration-induced by road traffic and the subjective responses to building vibration are compared. It was conducted that the ISO 2631-2 z-axis frequency weighting combined with a measure of vibration dose value (VDV = [integral of a4(t) dt)]1/4 may use a practicable objective evaluation procedure in buildings than L10 percentile vibration levels. It was also cleared that the L10 percentile vibration levels at the ground boundary of the regulation law of Japan Environmental Agency must be low levels.

Evaluation of whole-body road traffic vibration in building.

Level fluctuating vibration has been evaluated by the cumulative index L10, but some investigators suggest that the L10 cannot represent an adverse comment on vibration. In order to clarify the compliant, various factors involving vibration need to be analysed together by statistical methods, for instance factor analysis or quantum theory. The authors investigated the relationship between an evaluation index and human sensation of vibration in a subjective experiment in a wooden house. The subjects were exposed to vertical road traffic vibration reproduced with an electrodynamic vibrator placed near the house. The range of vibration levels at surfaces in contact with the subjects were from 50dB to 70dB in root mean square of frequency weighted acceleration level, i.e. the vibration level. Numbers assigned by the subjects and evaluation indices of the vibration level were analysed by applying the Stevens power law. The results showed that L10 or Leq (55) could become an effective index for the assessment of subjective perception of level fluctuating vibration in a wooden house.
