A 5-point Likert questionnaire ranging from “strongly disagree to strongly agree” questions was used to evaluate workers’ perception of the implication of safety management system in the organisation. The OHSAS 18001 internal audit checklist was also used to measure the level of compliance with the requirements of the SMS. Secondary data was obtained from document and safety report of the case study. The data was collated and subjected to descriptive statistics, t-test and row and column contingency (R & C) table to evaluate the relationship between safety performance and compliance. For compliance to SMS: General requirements, 91%; Health and Safety Policy, 95%; Planning, 93%, Implementation and Operation, 98%; Audit, 98%; and Management Review, 93%. The overall average level of compliance was 95%. 100 respondents participated in the questionnaire, 64 males and 36 females; 68 technical personnel and 32 nontechnical respondents. Descriptive analysis of employees’ perception resulted in: Safety satisfaction and feedback, 4.113; Training and competence, 4.182; Safety reporting and investigation, 4.212; Work Duties/Pressure, 3.989; Management commitment, 4.098; Safety communication, 4.171; and Emergency response and planning, 4.126. t-test indicated that there was no significant difference in perception between males and females, and the perception of technical and non-technical employees with p > 0.05. R & C contingency table was used to evaluate the relationship between safety performance and safety compliance. The result showed that there was a significant difference between safety compliance and safety performance since < . Therefore, safety management system will continuously improve safety performance. Hence, the effectiveness of safety management system cannot be overemphasized. The practice of health and safety has evolved over time, as a matter of common sense in several industries. However, this study opines that the implementation of safety management system requirements is instrumental to a sustainable continuous improvement in safety performance. The study, therefore, encourages organisation to consider the safety management system certification.

Remediating crude oil polluted soil in developing countries by environment-friendly approach has ... more Remediating crude oil polluted soil in developing countries by environment-friendly approach has attracted scientific interest. Sampled crude oil and poultry dung were obtained from oil pit and farm in Warri, Delta State. 500 g/kg of crude oil polluted soil was weighed into four different containers labeled A, B, C and D; the soil was amended with the application of sundried poultry manure at various weights of 50, 75 and 100 g/kg respectively leaving sample D without amendment as control for a period of 42 days. Isolation and identification process of bacteria strains were carried out using standard spread plate method on nutrient agar. Ten bacteria isolates were obtained from the amended and control soil in this research. Genus from pseudomonas and staphylococcus has the highest representation of three species each. The rate of degradation in the sample was determined by gravimetric analysis. The total petroleum hydrocarbon (TPH) present in sample D (control) initially was 4550.08 mg/kg. Samples A, B and C after remediation period reduced to the value of 3410.61, 2664.90 and 1598.95 mg/kg, respectively. The total hydrocarbon utilizing bacteria (HUB) increased gradually in the sample A, B, C and D to 7 × 10-4 , 7.9 10-4 , 8.0 × 10-4 and 5.0 × 10-4 respectively. The total heterotrophic bacteria count (THB) increased from 10 x 10-5 at zero week to 8.3 × 10-5 , 8.5 10-5 , 8.6 × 10-5 and 7.3 × 10-5 in the samples respectively. Physiochemical analysis of nitrogen increased from 0.04 to 0.17 mg/kg and phosphorous also increased from 1.72 to 6.73 mg/kg after the period of 42 days. This approach showed increased remediating effect of poultry dung on crude oil polluted soil.
